DO NOT try this at home! The
voltages present in high power amplifiers are LETHAL. Do
not operate an amplifier with the covers off and/or defeat the safety
interlocks unless you have a thorough and complete knowledge of high
voltage safety. Voltages of this level are unforgiving. One mistake can
result in serious injury or death. I'm not kidding.
have been warned.
I've seen pictures of 4-400s and other high power tubes under load on
the internet, but I don't recall seeing any good pictures of 3-500Zs.
So I decided to try my hand at taking some while I was working on my
Drake L-7. Here are the results. Click on the pics to see them
Pair - two 3-500Z tubes lit up, under load
- the plate is supposed to
glow like that
- Full power to the Warp engines, Scotty!
Beauty - the cathode helix and grid wires are clearly visible
