Memphis mojo 16-MC2000D output trouble.

[Perry Babin]

Try the numbers in the following manual to see if they're closer to that amp:

All transistors, diodes, and resistors test ok. I changed the 10uf 200v capacitor. Should I just switch all the 2sc3198 to the 2sc1027?

 

[Perry Babin]

How do the voltages shown differ from what you have in your amp?

 

[rhempz01]

In the schematic? I didn't look at it that closely. I thought it was just for a close refference? I'll take the vlotages and compare to the scheme.

 

[rhempz01]

i have pulled every transistor and capacitor in the muting curcuit and tested them all. everything is within tolerence, yet the relay is remaining open? so i am assuming the relay is bad? do you have a part number or a place to buy one of these>

 

[Perry Babin]

I asked about the voltage because it's possible that the relay isn't being told to engage from the control circuit.

 

[rhempz01]

It also now draws current if I attempt to power it back up, before the rail caps discharge?

 

[rhempz01]

Here is what I have under the relay

 

[Perry Babin]

If you have more than 12v across D501 (and therefore the relay coil) and the relay isn't engaging, the relay is defective.

 

[rhempz01]

Ok thanks perry. Do you know where I can buy it or one that is equivalent?

 

[Perry Babin]

Try this. Confirm that it's right before ordering..

Relays came out n today finally perry. I replaced it and the curcuit is now engadged the amplifier is working. I got 5 of them in case anyone ever needs one.
