Jl Audio HD 750/1 working, but in protect

[Achim1409]

I have this amp. It was working before. Now if I switch it on, the led is flashing red and green. Checked everything, amp is OK. Also the output stage is oscillating. But it blocks the audio input to the irs.. I found, that at the ps, the caps towards the ps fets are missing, broken of.. Any suggestions for the uf of the caps I can use? Expect, that this missing caps are disturbing the undervoltage protection or something else.

Which caps?

Photo?

The caps are missing.. The picture shows only the position.

 

[Perry Babin]

Every cap in the power supply?

 

[Achim1409]

Unfortunately yes.. But they are only connected to the ps fets

I don't have the information on those caps.

When I read 'broken off' and you didn't include the circuit board designations, I assumed that you were referring to electrolytics.

I got an email that said the caps were 0.0022uf@50v.
