Sajnos az eredetiket aranyarban adjak, igy gyartanom kell egyet. Talatam is egy elegans kis 4 pines csatit, de fennakadtam az eredeti csatlakozo labkiosztasan. Talaltam egy rajzot de nem tudom eldonteni, hogy a kabelen levot abrazolja, vagy a dokkoloban levot. Ha valakinek dolga volt ilyennel, es tudna segiteni, kerem ne tartsa vissza magat. Koszonom..

Mikor a MUTE hibat kerestem, volt olyan eset is, hogy nem futott meg a kimenet es szolt a basszus rendesen, de ujboli bekapcsolaskor ha nem halkitottam le a potit akkor kikapcsolt a rele, ha lehalkitottam akkor jo lett, de nagyon susogott, arra hasonlitott mint amikor FM radio nincs az allomason, van egy kozos mute tranzisztor az kapcsolja az osszes tobbit, ha azt kiszedtem akkor is megmaradt a susogas, szerintem visszafele jott valamelyik oldalrol ezert szedtem ki mindegyik oldalrol a tranzisztorokat, nem akartam bajlodni vele, hogy honnet jon a susosgas vissza.

(I still have to resurround the series III 901's. That's a job I dread!). What a beast. Anyway. I've recapped all the boards except for the tuner, replaced 2sc458's with ksc1845's, and rebuilt the power supply. Then I shut down, powered up direct to wall and set the Bias and center voltage to spec or at least tried to. Currently 0.1mv All biased to 15.0mv beautifully. Then I put a couple of test speakers to it. Switches were set for other and 8ohm for the test spkrs on the back. Voltages all boards are good. Voltages to RELAYS are consistant with board schematics. Which tells me the relay is probably good. As for the rest of it, Im stumped. No broken wires, no broken pins, no cold solder joints on the spkr switches or the relay board. Everything looks ok. I can't figure out WHY the RELAY IS NOT WORKING. This thing is REALLY A OVERBUILT SOB and has more crap in it than a 1980 and a 9090db put together. If there's anyone with knowledge of this receiver, any help would be appreciated. But I'll go over everything again on the 1-4 amps, protection and the relay circuits again. Thanks LarryI'm pretty sure it's a dirty control but some dis-assembly is going to be required to get to it. I've been reading some threads on how to get to the push button switches below the dial. Doesn't sound like it's gonna be fun. It's interesting that you mentioned a 9090db. I've read more than one comment suggesting that this Bose receiver was made by Sansui. Do you see anything that would suggest this to you. BTW, mine sounded great before it started having problems. Good luck with sorting it out. 'Really nice of you to work on it for your Bro in law.I'm wondering if this Bose receiver was made by Sansui?It is a nice receiver when running right.https://congviendisan.vn/vi/3m-mp8670-manual I used to listen to it when Pop's was alive. It did sound very nice with the 901's. ranch 22; It is a monster and a ROYAL GOLD PLATED BITCH to open up to gain access to the boards. Just to get the front panel off. Remove the top. Remove the side panels (3-4 hidden screws per panel), Remove the bottom panel. Remove the knobs, and the 4 center slider handles.Then lift the dial pointer (tune to 100mHz) out of the hole. 3 screws on the bottom, then 4 screws on the top (2 each end). Start pulling on the right side as you face it. It should slide off fairly easily. WATCH OUT FOR THE BOSE LABEL WIREs on the left side. They will be tight. (Undo wire loom to make slack. Now you can access the push buttons from the front. If you need to access the backs remove the panel. 2 screws on the front and 5 on the bottom of the board. They didn't make this thing to be worked on for the most part. Definately get the manual.I'll shoot you a PM soon. Any luck with the relay problem?So standing around in the basement working on gear will have to wait a few days. Went to the Dr's today and I've got Anti-biotics, and enough pain meds to kill a horse (or at least knock down the hacking cough some) so I'm good there. LarryI thought I just had a cold pre Christmas but it turned out to be the flu. Get well!I told the Cardiologist's I got Dollar Store Genes instead of Wrangler or Levi''s but he didn't get it until I explained it to the dumb SOB!Then I started testing each resistor, cap, transistor, and diode left and followed the circuit up to the RELAY. Figures it would be the last thing checked. Replaced it with a uf4007and CLICK!!! G.D. diode had me chasing gremlins for a friggin week.:nono::tears: Gonna button it up after rechecking the bias and offset, and tell my Brother in law the next time I see the insides of this SOB it'll be 200 years TOO SOON!:worried: LarryIf it does that without problem, it's off to my Brother in law. Some pics. Nice contemporary look.https://academyocgc.com/images/bose-spatial-control-receiver-service-manual.pdf The large one on the right is for the spatial control. Power Supply Board and the Spatial Control Daughter Board which plugs into the Tone Control Board. Total PITA to work on. Made in JAPAN by TAMRADIO for BOSE. Looks kind of Sansui-ish in some ways. Speaker Relay board (upper) with Speaker output's for 901's and others. Main amps (4) are on the lower board. I'd rather change the head on a 74 VEGA in a snow storm than work on this board again. The VERTICAL Board to the right of the Tuning VC is the POWER SWITCH ASSY.Like I said i n the previous post, I'd rather change a 74 VEGA head in a Snow Storm(No Garage) than work on this again. Overall I'm not really impressed with it. Build quality is good, but layout could be better thought out. Aesthetically it's a very nice looking unit. The Blue-Green Dial reminds me of Early 70's Sansui's. Push button Controls under the lower lid have a good feel to them. WTF did Bose use sliders for the Tone Controls and spatial enhancement control????? Pots would have been a major improvement. But it wouldnt be a BOSE then(Gimmicky!). Protection Relays will not turn on until the SPKR switches are turned on. Standard fare for 1980-81. All the caps dated 8044 to 8052 so this is probably a mid spring 1981 model. The tone controls are really set up for the 901's and with regular speakers the tone is lacking Bass even with the Bass control all the way up and Loudness engaged. This is on NLA Bullnoses. My SX-434 has better tonal quality. I haven't heard it recently with 901's but seem to remember it sounded pretty good at Pop's house when he was alive. So it's probably a component mismatch. Bose will not work on these anymore, so if you have one, either be prepared to lay out a good amount of cash or learn how to work on it. This unit is NOT FOR A NOVICE. I would rate this as an Intermediate to ADVANCED Hobbyest who has worked on comparable units for a while due to the assembly complexity. RATING: Aesthetics.7 of 10 Build Quality.http://recamonde.com.br/wp-content/plugins/formcraft/file-upload/server/content/files/1626c59acd4718---carver-boat-manuals-download.pdf7 of 10 Ease of REPAIR.3 of 10 Parts availability.9 of 10. Overall Rating.6.5 of 10.It wouldn't power up at first-sticking solenoid. I now get to replace the source indicator lamps. FUN! I think it may get a re-cap while I'm in there.My right channell is fussy, and it is going to need to go to the shop. We have a good tech here in Pensacola. My 71 Vega is long gone.Perhaps that was your expression upon seeing my post.I already uploaded the Owners and Service manuals to HIFI ENGINE.com If you have some DeOXIT (F-5) FADERLUBE Spray some into the slot in front sliders (bass, treble, balance) then work the slider back and forth 20-30 times. Don't use much. And don't do the spatial. It's not an actual slider like the other 3. Take off the top and spray some DeOXIT (D-5) into the ROTARY POT (Volume). For everyother control on the front, the Front panel has to come off. DO THEM ALL as the signal path goes thru all of them. Larry. This is the Bose Spatial Control Receiver which doesn’t seem to have a model number on it but I believe it is considered model 551. It puts out 100 watts per channel and has a built in EQ for the Bose 901 series IV speakers. Bose also made a model 550 that had a built in EQ as well but only sported 40 watts per channel and had no spatial control. The front of the receiver has a flip down panel to access the controls. The power switch is on the back of the unit and when it is on you can still turn the unit on and off by touching the Bose logo on the front of the unit. These Bose receivers aren’t that common and it’s probably due to the fact that not that many were sold. The sales copy explanation behind how the “spatial” effect worked was somewhat complicated and, of course, they were really designed to work with the Bose 901 speakers (though they could work with any speakers). Many customers probably opted for a more simple solution to their audio needs. Nonetheless, these receivers do sell for decent amounts of money.aothuatdanang.com/upload/files/casio-edifice-efa-117-manual.pdf In fact, if you’re a Bose fan then one of these units is probably a necessity.And I believe the previous owner told me years ago that he left channel was flakey and had went bad some time back. His wife and mine work together, and she just gave the my wife to give to me. I was wondering if anyone knew where I could get hold of a schematic or a service manual for it? Reply Mine didn’t have any markings and the manual turned out to be correct. Reply I’ve written quite a bit about this fine receiver (and own several of them) and would like to point out the unit is the “Bose Spatial Control Receiver Model 108787”. The Model 108787 definitely had an original version (considered a Series 1 though not marked so) and then also a “Series 2” later produced and quite possibly a Series 3 (though I’ve only seen one single photo of one). Cheers. Lee of NJ Reply I’ve never seen one of these “live” but it sure is a fine looking receiver. You don’t hear much about Bose receivers as it seems their speakers hog all the publicity. Reply I’ve inherited the receiver and just found a pair of 901s with blown out surrounds on the drivers. Anxious to get it running again and enjoy the crisp sound that the system used to produce. If you haven’t had the pleasure, take the opportunity if it comes. I haven’t heard a better system. Reply Looking in Toronto Canada for a repair person for this type of receiver and 901 speakers. Can anyone help me?? thanx! Reply Speakers were replaced with new 501’s, if any one has any interest E-mail me with a serious offer. Still great sounding.I have the 901 series 4, a set of 100J and 701 series 4. I have them running on a ReVox b285 but I would like to experience the spatial effect. Thanks! Reply Now have 4 901s to complete the set. It controls a mild signal delay to the second set of 901s. Assuming you find an SCR in good shape, you will not be disappointed. Reply I bought this off ebay and it had a blown channel and DC voltage on it.http://lookupagency.es/wp-content/plugins/formcraft/file-upload/server/content/files/1626c59b3ecfde---carver-boat-manuals.pdf I replaced all caps but it was no better. Tested the outputs and one side has 2 bad finals and there is another bad transistor on the board. Unfortunately to do my testing I used some cheap speakers and they are fried now due to the DC. I think I can get one side running now but really could use a schematic. Anyone?? Thanks Reply Sometimes it recovers itself after 10-20 sec., sometimes it doesn’t and I have to switch it off from the button on the rear. Does anyone have any idea how to solve the problem?? Hernando, would you please help me with schematics. Thanks! Reply Thanks in advance. Is it the 100 amp per channel model? Reply I pickup two pair of 901’s IV and have just finished re-foaming them. Would love to hear them hooked to a 551. Reply I just found out that this huge speaker that I have been carrying around for years is an original Bose 2201. The serial number on it is 55.if anyone is interested, or can suggest where would be the best place for me to find out the value or suggest the best place where I could sell it I would appreciate it Reply It was made in 1966 and I think it was Bose’ first speaker. They didn’t make very many. So, as to the value I don’t know. You could wait until another one comes up on eBay and see what it sells for. Or maybe Audiogon. That’s about the only way to really tell. You could always list it on eBay yourself on auction and see what you get. Use a reserve if you don’t want to sell it below a certain price. I’m not sure but I think they came in pairs (or quads) and had a EQ with them as well. Reply I was thinking about selling it on eBay but I didn’t even know what to start the asking price or set the reserve at. I checked with audiogon and they’re blue book and they have noticed things so I’m kind of up in the air as to what to even start a price at. I called Bose Direct they said I could pick any consumer home theater system they had in exchange for the speaker but they couldn’t offer me cash LOL.http://www.oknookna.pl/wp-content/plugins/formcraft/file-upload/server/content/files/1626c59b9bae66---carver-c-1000-manual-1.pdf I think that this might be better than any homeentertainment system if they could offer me but I’m not sure. I have never hooked it up before going to do that tonight wish me luck Reply Ive had it for years and used it with 901 XI’s. I cant imagine a better sounding system. I haven’t used it in years (since I Moved). I just hooked it up and it still works, but am getting nothing out of the left channels. The balance slide seems sticky, so maybe thats all. I have both of the user and owners manuals, with the flip down panel like the receiver. I would be interested in selling.I’ve hooked them up and they are a joy to listen to. Still have original manual as well and I’m willing to sell. I’m in the Columbus Ohio Area if you’re interested! Reply Located in Tx. Reply I’m the original owner and have original manuals. I don’t know what a good asking price is. It is in very good to mint cond. Reply NEEDS NEW FOAM RINGS Reply Years ago a Bose rep helped me replace my original series V speakers due to defective cone material (foam). The lighting inside the receiver is out. I’m in Atlanta. Makean offer for a package deal. I can photograph if someone’s interested Reply I have been told that part 1 and part 2 labeled on the speaker only comes into play if you use the Spatial Receiver. So can I have two part 1 speakers or do I need a part 1 and 2 for it to sound right? Reply This is the 100 watt version. This receiver is in MINT condition. Last used about 10 years. I’ve had is in a box stored in my garage for 10 years. It works. It comes with the original sales and owners manual. I also have the service manual, printed. I may even have the receipt if I dig deep. I sold the 901’s speakers years ago but kept the receiver. No scratches or water stains. Due to scams.
