Don't be too hard on the guy. That fan is just like the one in the SB200
and not even as close to the tubes. It looks like the guy used what he
had or could scrounge to build it. Even home brew plate caps.
The chassis looks like it was salvaged from a few other projects.
Obviously a "budget" project amp. And I bet he learned something while
making it work too! Some of my early projects didn't look any better.

Hey!
I'm hereby cancelling the order for my new Sx77 for hotel room-portable DXpedition use.
The homebrew on ebay just fits the bill. And the bid is still hovering around $15.50.
Why spend $5K on a new Alpha '77 ???? Just the transformer in the 'Sx is enough to put my back out just looking at it with that cute rope handle.
I bet the HB '811 set all tubed up and humming weighs less than the HV XFMR in the '77.
I'd want it just for the tube fan alone. Those metal blades are right near the action. I wonder if distant stations when hearing the amp think it's on board a spacecraft, or maybe HF EME with true libration.
