Question about Audio Players & Recorders
I have a Carver M-400 power amplifier that has died. When you plug it in, you can see a sizable spark at the base of one of the large capacitors behind the power transformer. The amp then pops (if you have a speaker connected) and causes the LEDs on the front of the amp to flicker and jump to all various levels.
I cannot see any components that are destroyed (IE - bulging cap etc), but I have not tried replacing the cap that sparks (because I'm not sure if that's the issue or a symptom).
I bought the amp for under $50 some years ago and have an estimate of a significant amount more to have it fixed, so I'd rather try myself.
Sizable sparks at a cap~ base?? That sounds like there may be a dead short somewhere and/or catastrophic failure of the caps~ (not always visible on the components, use a multimeter to check the terminals if they are shorted.) If there is noting else that has failed in the amplifier other than the power supply* (*if applicable), it is repairable. Otherwise good luck finding the other fault(s)*.
