82E194 Schematic needed
« on: March 04, 2025, 11:13:21 PM »
Hi, This small daugther board can be found on some 82E01 Input cards as a mod to presumely retrofit the input to meters function.
Has anyone got the schematics for it or some info?

Thanks in advance
Michele

Hi,

Do you know which op-amp on the 01 this replaces? I can probably work it out from that. It seems to be switching the gain of the op-amp which is a bit odd. I'm sure I knew what it did at the time...it has the feel that it might have been one of mine...

Thanks,

It seems like it replaces T3 in the Line Trim section. Have the same boards all across my Console.
I will ask my SSL Tech on Saturday if he knows more about it.

Best,
