I recently had reason to look at the purity of the B+ supply voltage for my
Ten-Tec Titan amplifier.
I once owned three of the original Titans. Hum I've experienced was
caused by one or two bad lytics in the HV string. Easy test is after
everything is discharged, use VOM going one direction and then the other
one each cap, noticing the extent of charge-discharge for typical, then
going back through to note which is (are) bad. I've never experienced
more than two.
Note that a 90% schematic is on my website. k9yc.com/publish.htm Scroll
