Hitachi (Marantz) 50TB1 CRT testing/specs

[Gene[_4_]]

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
