Ringing on 2235 100 volt supply
Hi Tek group members!
I'm an new member and just acquired a 2235 scope. It works great except it has an intermittent horz sweep problem. Checking the power supplies, all were in spec except the 100v supply ripple at 90 p-p, spec is 40 p-p.
Mainly out of spec due to ringing on every other cycle. Anyone seen this before? So far I have only replaced the cap and diodes in this supply. I'll cover the sweep problem in different thread.
