Eclipse 3321

Have this amp up on the bench ..

The amps power led will flash green ..

The regulated voltages are around 2 volts both positive and negative and the voltages are pulsing ..

All outputs and drivers test fine ..

Any ideas where to start?

Are 318d's installed at IC2 and IC3?
If so, you might try pulling them and see if your regulated voltage returns.
I had a similar amp with similar issue that had a bad 318d that kept slowly killing the regulator transistors and related Zener until I finally replaced it.

Smart man Thanks for the info thats the problem i pulled them amp powers up perfectly.. and regulated voltages came back

do you happen to have the full art number?

Likely NJM318. Confirm before ordering. If you cannot find those, the LM318 may work (compare datasheet specs).
