Title: Yet another Tektronix 465 repair
Post by: MarkKruetzmann on November 07, 2019, 05:10:36 pm

Hi!

I recently bought a dead 465 which now sits naked on my bench. I measured the low dc voltages and they are all down. Yippee! Finally something that is actually broken and needs a repair!
Anyway, the service manual I have seems to have no circuit diagram of the power supply, only the detailed block diagram. Does anybody know a decent service manual available online? I'm asking because there seem to be some options and I don't want to dig through all of them just to find missing pieces or faults.

Mark

Start with the +55V reference. If it's low all the supply voltages will be off.
