Out of circuit, Meg ohms one way and k ohms the other. I remember I had got 2 different kinds of 1n34 diodes when I restored this set,one had a red cathode end and the other a black cathode end so I just changed that diode to the black since I had the red one in there and the pic is better . But I do remember that someone had started the restoration and they used ceramics for hv filters and horizontal couplings and since finishing the set the picture flickers in different ways on scene changes so I'm thinking those caps have to go. The verticle couplings are correct. I believe the horiz ceramics used in here are doubled up for the capacitance changes when warmed up but they still may be creating problems.
