Hello folks,

I retrieved a Tektronix TDS-620B digital oscilloscope from the dust-bin of my university today. The unit
is completely dead. Fuse (6A/250V) is ok. The power-supply is really sophisticated and I think servicing
it without a service-manual is impossible.

Maybe some of you guys has an idea where to get the manual or what could be the culprit. There is a sticker
which shows all output voltages of the power-supply, but I have no idea where to test them.

Any hints ?

Adrian
