Hello All,
Delco 2700 series, 16006776
Looking for a repair person on these, prefer in Canada.
I have 2 which both power on and LEDs OK. 1 has faint sound at Max Vol and
other none.
I suspect the amps for both. I have the the complete Delco circuit diagram
but I am no expert electronics tech. without tools.
Just have a basic multimeter.

Any contacts appriciated.

Thanks,

John
 
Well since nobody replied I will give an update.

I had disassembled both radio's and discovered the PCB board with the left
and right amps. So tonight I had to use a solder iron and disconnect 2 wires
on each radio so I could swap ot the amps. Tomorrow I will connect to the
car to see if I have made any progress.

Cheers,

John

Update
After work today I had a chance to hook up my radio and to my surprise I had
sound! Yes Music to my ears. Well not all that good since I only had front
right. The rear is not connected as I bought 4x10 < 6x9 adapters and have to
hook up some speakers. I am hoping the left side is a loose wiring problem.
The Tape deck is also not functioning and able to accept the tape. My other
radio tape mechanism my work better.

I try tomorrow.

Cheers

Found the problem, was a wiring issues 2 same colour wires but different in
gauge. now all speakers work, so my plan worked after all when
transplanting the amp/circuit board to the other radio. the tape was
transplanted and is working but still needs an adjustment. The CB radio part
I am not sure if is going to work.
I might need a CB antenna.

Good that you got it repaired, but it's doubtful that the guage was
the issue with a go-no go problem like yoou described. Likely bad
connections, as you mentioned earlier.

I think he meant there were 2 wires comming out the back of the radio and
they were both the same color, just one was larger than the other.. Like a
illumination wire being grey along with a speaker wire just one was larger..
