Got an HP 2382A terminal I'm attempting to resurrect. I get no video, no heater, no high voltage. What I believe to be the horizontal output transistor appears to be bad, but I'm not sure if this thing contains internal diodes that might be throwing off my testing attempts. It's labeled "1854-0900." Anyone know what this actually is? (Anyone have a service manual for this terminal?)
It's possible that the video section is identical to that of the HP 120. According to Tony Duell's schematics, the HOT is a MJ10006. The HP9816, also similar in shape, uses a BUZ45.
The HP150 uses HP part number "1854-0948" which is also a MJ10006. Christian
