I found this TV at an estate sale today....it has a new replacement RCA black matrix CRT but there is a problem in the high voltage regulator circuit so there is no HV at the CRT. I checked the horizontal output circuit by holding a neon lamp near the plate lead and it does glow. Need to check out the 6BK4 grid-cathode circuit.
