Mark,
Thanks for the help! Greatly appreciated!
I am thinking the Bias pot is R873, its labeled Beam. Last week I found that pot had come apart. No trace. If I pressed down on that pot the trace came alive. I ran the scope with a 20K pot and it functioned. Then I wired the circuit with fixed resistors. 25k, 25K with a center tap until the replacement pots arrive.
I checked the 1uf capacitors with my Sencore meter and do not suspect them to be the issue. I will order replacements. The ones in there are axial and the ULD you recommended is radial. Is that what you had in mind?
I have ordered the 1N4937 diodes. It was previously recommended to replace the diodes in the DC Restorer circuit. I am not sure what the DC Restorer circuit is. Can you point that out.
Thanks!
Barry
