Im working on a PV 8.5C that was worked on somewhere else.
I fixed the issue in the unit with one output bad. repaired all of it and was doing a once over before putting it on the Variac.
I noticed that U101 and 201 were gone. These are the dreaded 70413080 / Hand picked LM3080N's OTA amps. I'm a bit hesetant not to replace them but at $15 for each adapter module I'll go over budget for repair on it I also dont like the thought of it not having the limiters.
