Het, I started this and we're not talking about CB amp.
We're talking about Tetrode amp with tube side of output tranny
between screen and plate anf HV applied to screen :-)
Or is this a common CB circuit???

| The 4CX250 amp looks like a CB amplifier Skipp. It certainly can't
| be a very good amp for ham radio.
|
| It takes 1-5 watts of drive, and worse yet has no screen regulation,
| current limiting, or metering.
|
| I certainly hope not many are used on amateur bands!
|
| It looks like a copy of a CB amplifier marketed under the guise of a
| "amateur linear" by a company that sold out-of-band crystals for
| CB radio's in the 70's and early 80's.
