I have just purchesed and recieved 5 NOS RCA 6GV8 tubes in 1960's boxes
with 60's lettering. The tubes are made in Italy and Not in the USA.
I tried to do some research on 6GV8 Tubes and None are made in the USA.
They are made in Germany, Italy and Holland only. I wonder why this
tube was never made in the USA.
I also did some checking for substitutes for this tube and their are
none.
This is an odd tube.
Not many radios use this tube.
I have a RCA Mark Nine CB radio from 1966 that im restoring that uses
this tube as the final output tube.
Does anyone know of other radios or TV's that use this tube ???

6GV8 is the same as ECL85, an European designation for a triode-power
penthode, with a 6.3V heater.

I've not seen many of them, though.
The 300 mA heater version, known as PCL85, was more widely used in TV
sets.

Why anyone would choose such a tube as an end stage, especially in a
USA-built radio, is beyond me.
Are you sure this is the original tube that belongs in there?
I'd say a ECL82/6BM8 or even ECL86/6GW8 would be a wiser choice, and
at least better available to anyone all over the world.

** The 6GV8, 6GW8 & 6BM8 all have very different pin connections.

No " plug and play " possible.

Fairly common in European TV's as the ECL85. As a RF amp the pentode is
like a beefier 6CL6, and this class of pentode is working pretty nicely
at 27Mc still so I'm guessing it was a good match to a CB.

Does the CB use the triode section as an amp for modulation (maybe
screen modulating the pentode section) or something?

Yes , Triode section is being used on this RCA Mark 9 Tube CB Radio.

The 6GV8 was used in Tektronix 529 waveform scopes. TV stations used them extensively in the
60's-70s in control rooms/transmitter sites. I've seen US branded ones but made in Europe.
