The osc. is indeed on the weak side....And so is every other 6U10/6AC10 I was able to find in my cursory tube search. Would not have thought to test the osc when the H output grid drive is spot on.
I've never owned a working VTVM...They always cost too much, get sold before I see them, or end up not working...Some day I'll fix one of the junk VTVMs I have.
The Boost voltage is decent. Tomorrow night I'm going to try to bolt the chassis in and get the bottom panel off so I can work on it efficiently.
Till then schematic fragments for the curious.
