You mean you didn't operate with the cabinet off to see the tubes glow?
Back "in the old days" I saw many a high powered amp operating
"on-the-bench" with no cover during the test phase which sometimes seemed to
go on forever. Back then, we didn't think much about it, now days we don't
think much of it.<:-))

I never had any problems and my dipoles were only 20 feet from the TV
antenna. I only operated 80 and 40 meters. Of course TV was all B & W then
and the nearest station was about 60 - 70 miles which made them all "fringe
area". OTOH the next nearest TV set was over a mile from us. I think ours
was about number 6 for the area.
The only real TVI I ever had was some years later when I was running a 6C21
pulse modulator tube on 20. My neighbor's TV antenna was about 50 feet from
the tri-bander and of course he was pointed SSW at me to watch chanel 6,
while I had the beam pretty much NE for DX. That didn't even work running
my HT-37 barefoot. Thankfully our hours worked out so they were seldom
watching TV while I was chasing DX. I don't have any photos of any
incarnation of the station(s) when I first lived in Midland (62 through 66).
Which reminds me, there was another ham about 5 houses down from me. I don't
know what he use for a receiver, but he said when I was on 40 with the amp
the whole band would go dead for him.
But... Speaking of hot leads. I had the HT-44, SX-117, and PS-150 power
supply for a while. You measure plate current by measuring the voltage drop
across a resistor in the B+ line. They thoughtfully provided meter jacks on
the PS chassis. So, I was up on the bench with the equipment, holding the
meter leads in place with my left hand. I had to reach across to the left
with my right hand to move the meter (which had a metal case). Unbeknownst
to me, my fingers had slipped down on the probe tips.
I remember that sucker really bit me and then... I woke up on the floor. It
took several minutes to get my breath back after climbing up into an easy
chair. Whether true or not, I don't know, but I believe it was the impact of
falling 4 feet onto a concrete floor that started my heart.
