Wow, talk about over-complicating things...
You don't need a scope to do this test. Just a wire plugged into any handy audio amplifier will do. One way will get you more hum out of the speaker

Re: Looking to buy HP6268B 40V 30A Power Supply
Alwyn
I use my 6271B all the time with My GRC 106 Military transceiver. Puts out maybe 350 W with two 350Z tubes.
But the GRC is so loud (fan) that I would not notice any PS noise.

Re: HP200CD oscillator
X-rays don't happen at such low voltages. The blue glow,
if on the envelope, is fluorescence caused by electron bombardment.
If you get a glow that is inter-electrode, it is ionized gas.
