Tektronix 2335, no trace, no beam

[TekMan]

My good old workhorse 2335 scope just quit the last days: fault is on
the A15 boord (HV): All diodes and transistor are ok checked by curve
tracer.

So it looks I won't get forward without a schematic. Is there any
helpful soul around willing to do a scan of the two pages: A15
schematic and the parts location?
This would help a lot.

Please reply here in the group.


TIA,
Andreas

Thanks to Len, I received a scan of the HV schematic. The HV module
and the thick-film resistor array are the cause of the malfunction.

Thanks for the help, Len!
