[Boatanchors] Trying to identify the origination of a real nice heavy PA tuning deck

[Bill Mellema]

 Guys,
I recently found a partially built homebrew 2X 4CX150 ham PA amplifier. The PA tuning is a separate section that can be removed with a few screws. It is built like a tank and can easily handle 2KW with the very heavy hardware and switch contacts. The PA section is definitely commercial not homebrew. I would like to find out if it was sold as a single assembly or pulled from another ham amplifier. The assembly contains ALL of the output PI network, tank switching and loading capacitors. The load capacitors are on a pinion driven rail that actually controls two caps at the same time. If anyone can thinks they may be able to help me I can send pictures. Please contact me direct.
Thanks In Advance,
