Hi all. First post on this board, thanks for the read. I am working on what Appears to be poorly rendered schematics with alot of assumptions in the drawings. Let me get to the request and then explain the discussion of this thread.
A recent power failure has faulted the amplifier. Upon opening I have discovered that the low voltage opamps were not getting anything more then 5-6 volts across both rails.. (should be 30vdc). Now im showing a -15vdc on one side and 0v on what should be 15v..
Not knowing where power is sourced from directly im assuming a bit that i could have a shorting op amp or the circuit is in a muting or protect mode.
Im trying to discuss the problem and diagnose the amplifiers pathway of power. Reading the schematic shows a few things, but i would like to discuss with you all to solve my issue but learn more of this design .
