Eden E300 Low, distorted output

[ca7922303]

Sprayed all pots, jacks with contact cleaner, no change. Noticing that mp3 volume increase/decrease does almost nothing to the output of the amp. Nothing on visual appears wrong.

Is this a tube amp, SS ? Line in line outs?

These look like Class D mini amps. website doesnt say much

Check the effects loop connectors.

Check the effects loop connectors.

Jumper them with a short cable.

Check supply voltages. Should be around +/-15V at IC's on preamp board; and +/- some higher voltage at the power transistors, probably in the 35 to 80V range.

That looks like the standard Eden class B power amplifier. I doubt it is faulty however, they do suffer from poor switch contacts, contact cleaner will cure that and bad connectors on the interconnect leads.
Check the mute command line; Pin 5 of P2. Should be near zero volts or negative to open the Fets and allow signal to pass.

Thanks for the info. Out of town working this week. Will check this on the weekend.

wow looks like such an old design for a current model. Im actually an authorized repair center for Eden (I think) and Ive never had anyone bring one of those in to me. Thanks for the pics.

Only P2 I'm finding does not have a pin 5 I don't believe. Can you verify where it is. Thanks.
