Chortle. I received an eyebrow-raisin' clip from one of his posts from
an unfan, which is why I showed up here. Where there's smoke,
there's.................

Better suppressors is not going to help the shorted tube and zener, but
we might be able to lick the problem with the fil/grid short if there are
no other problems with the tube...If the short is intermittent when u
bang on the tube, we might be able to fix it with our centrifuge. If the
shorts looks like a weld, the tube is history.

Suggestions on unamibiguating them are welcome.
The biggest time-consumer is reading the plethora of pages of
information and instructions. Some people don't. This is one of the
reasons I have a moneyback guarantee. Believe it not, Carl, some folks
do not wash off the nichrome soldering flux residue.

Reading time---maybe an hour. Soldering is anybody's guess. Henry amps.
are time consuming to disassemble.
Another problem is not installing the glitch protection components. I
think this happens because some people assume that a resistance-wire VHF
parasitic-suppressor is a miracle-sure-cure. IMO, a suppressor retrofit
kit reduces VHF voltage amplification by about half in the SB-220 and
TL-922---and in the AL-80 and SB-1000 by about a third. Such an
improvement is worth having, but it is no guarantee of absolute freedom
from future VHF parasites---so leaving out glitch protection carrys risk.
