Wow. I would be afraid the fire that one up. It looks like the plate vac
variable and coil are at plate DC + and the blocking cap is after the coil.
That means the vac variable has to withstand the initial DC plus whatever
the plate is swinging. Now the RF Choke is so big that it has to be
capacitive in value which is not good in my opinion.
The rest of the amp looks like it was manufactured by a professional company
and someone got in there with a pair of wire cutters, hack saw, and other
tools
and wanted to score big on CB.
My 2 cents...
