Amp powers up and produces both + - rail voltages also produces the 5 volt regulated voltages..

Cleaned all switches and moved the pots up and down about 50 times..

Amp has very low output ..

Any ideas?

Do you see any 2N... transistors near the 8-pin op-amps?

Post a photo of the board.

S Merlington · 2013-01-13 6:02 am

I will post a pic of the board as soon as my camera battery is done charging..

There are 2 2N5639 transistors near the op-amps

What is the DC voltage on the 3rd leg?

S Merlington · 2013-01-13 6:58 am

2N5369

Leg 3:-0.13

2N5369

Leg 3:-0.13

The mute-drive circuit isn't turning the muting transistors off. I don't have anything on this amp so I'll have to wait on photos before I can help.

S Merlington · 2013-01-13 5:58 pm

Both of them are shorted between all 3 legs..

Is there a good sub for theese ?

rrae · 2013-01-13 6:28 pm

nte123a should work?

S Merlington · 2013-01-13 8:00 pm

Thanks but i never use NTE parts in amps ...

They are expensive and some amps do not like thoose parts and have had bad outcomes using thoose

Heres some pics of the board...

Dont know if its normal or not for the 2N5369's to read shorted across all 3 legs ?

Perry Babin · 2013-01-14 4:13 am

It's normal for them to read as very leaky between legs 1 and 2 but you should not read a short between 3 and the other legs (out of the board).

S Merlington · 2013-01-14 4:31 am

Heres on all 3 of the 2N5369's out of the board This is in Diode Check

Legs 1-2:.002
Legs 1-3:.001
Legs 2-3:.002

Probes reversed

Legs 1-2:.002
Legs 1-3:.001
Legs 2-3:.002

If theese are defective is there a good sub replacement for them or do you know where i can get the orginals ?

Perry Babin · 2013-01-14 5:30 am

Does the amp work normally without them in the circuit?

Why do you need a sub:
512-2N5639

S Merlington · 2013-01-14 9:14 pm

Yes the amp works fine with all 3 of the 2N5369's removed..

Hi, I need to know the value of the resistors R27, R26, R10 and R11.
thank you very much.

S Merlington · 2013-03-23 12:49 pm

Start a new thread and post a pic of the area/ areas u need to know the value of the resistors
