Ok. I will change the plastic insulator for mica, but I am very skeptical as to whether that alone will restore its adjustability. We shall see.
Oh, BTW - the plastic in there now is not Plexiglas, it is a very thin yet semi-stiff plastic such as used in various products you can buy at stores. You know, very thin, but allows you to see the product inside.
As for question #2, I guess I really should measure voltages at the 6H6G 2nd det-AVC tube cathodes, and at the "B-C" voltage divider where the circuit is also connected, find out what is going on, and report back later.
