Hitachi (Marantz) 50TB1 CRT testing/specs
Anyone ever see a spec sheet for this tube? This CRT was used in Marantz 150
and 4400 tuners. I have one I want to sell, but I need to test it first. Just knowing the pinout would help. I have a 4400 service manual, (Thanks, Audiokarma!) but it does not show the wiring to the tube, can anyone tell me how the P900 Scope Display Amplifier Assembly connects to the tube? I have not been able to find a 150 service manual. Thanks, -Gene |
