Default HV Power Supply - Test For Ripple



Thanks Bill. I wanted to use my DVM (Fluke 87), but don't know the
original specs on the power supply. I have been trying to find them
on the Internet.


Here's the schematic in case you don't have it.

If it is hum distortion on receive as well the +275 line and the -110
line would be most suspect. I rebuilt a couple of Galaxy supplies
similar to this one and if you start finding bad filter caps it makes
sense to just do a clean sweep of all of them.

I don't know your meter but indeed check to make sure it can handle the
range for AC+DC!

Good luck,
Bill
