Interfire IFD 2000

Dr Zeus · 26th July 2011, 03:13 AM

I've got this amp on my bench which powers up just fine, with positive and negative rail and regulated voltages. The opamps all seem good with no significant DC on input or output pins. Audio can be observed on most to all of the opAmp input and output pins.

Unfortunately this amplifier produces no sound. There doesnt seem to be any sound traveling to the output transistors.

Know anything about these amps?

There was another amp similar to this with a similar problem but I don't remember enough about it to know what to search for. I don't think it was an interfire. Maybe someone else here recognizes it and can find the other post.
