Thanks Bill.
No the large circuit board is a WD7S Triode board. Has all the metering, filament timer, relay switching, grid and plate overcurrent, etc all on one board.

No stepper motors all manual tune.

The plastic chains and sprockets are for the 10 turn pots that act as a turns counter.

Thanks and 73

That is a truly amazing piece of work. I notice the large PC board
which is apparently the controller for the stepper motors. Did you
build that yourself too? That must have been as much work as the rest
of the amp put together. Just curious.

I built a basic homebrew manual tune 8877 amp a few years ago so I
know how much effort you put into it. You have created a masterpiece.
