First off, the Full sized, NOT mini, Jones plug, is rated to 250VDC, pin to pin.
BUT, that is NOT what I said.
The Russian unit IS an external amplifier!
Solid state power supply?
You need to feed it 12 volts with 14 amps just for the filaments.
The Russian D amplifier is a modular unit used in Russian designed radios that provide all of the voltages needed from 12 volts.
So, the pi circuit is being used, what about the high voltages?
That is what the UHF connectors do, they carry both whatever signal and the high voltage.
This is called the ''Russian Stinger".https://www.youtube.com/watch?v=gBEr2XMPI1E
I do know of any videos in English of the Russian module and really have concerns over people installing them, some guy got killed!
And, yes, he was a ham!
I do NOT agree with the average ham or CB type "play" with such a device unless they are fully informed.
There are voltages that can kill!
A UHF connector can carry 1000+ volts but is rated to only 500.
Modern Telflon connectors do better at high voltage.
But, we went from cheap tubes (813) to 6146?
TV sweep tubes are getting very expensive, so I tried the sweep module out of a multi standard TV/Monitor CRT unit.
I watch what is being done.
I am not the engineer, I just watch, learn, and copy, and I will be the first to tell you that.
I sort of understand the theory, but need to look at schematics, parts values, etc.
And, like it or not, I am following the lead of CB types!
Most do NOT want to be hams!
Look at the attitude of hams, they are filthy and in every one else's business.
Look a Dayton and the cheap Chinese radio threads for proof of that.
But, I can only be totally honest, I do not fully know what I am doing.
I can sit and watch, and learn, and replicate.
The chance that I could stuff a 6146 into an FT-101, without an example in from of me to copy, is zero!
