I presume the original problem on this set was Vertical O/P IC and open R570. I have replaced these, but set will only activate the B+ relay, and then relay opens again. High Voltage does not try to start. I have removed F501..B+ Fuse and have the same symptom. Horizontal O/P not shorted. I don't have a Manual for this set, any tips would be appreciated. Or a scan of the Power Supply..and/or Regulator, Thanks -Ed- Tel-Tek Electronics Ontario-Canada teltek3@xxxxxxxxxxxx ----------------------------------------------------------------------------- This Email List is accessible to the general public through search engines.
