Hello. By chance does anyone have a video clip of this amp in action? Thank you.

That's a one of a kind amp. I don't have any videos.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

This amp sounds good as is but if I was doing this conversion today, I would put an Ampeg B15 preamp in it rather than the Fender preamp. Why??? Because the tube lineup looks more like a B15, but mainly, because those potted transformers just have that cool B15 look.

So, what project do you have in mind? A conversion? A scratch build? Something else?

I was thinking of a scratch build with full wave bridge instead of rectifier. Also adding a master volume and using a Russian 6N6P instead of a 6SN7. I've used them in previous builds and they add punch and bottom end.

this was my take on Sluckey's rockola.  got pretty good reviews from the guitarists, made it into the wild
Went Class C for efficiency

I like to convert old octal PAs and mono HiFi amps.
Here is an amp I built on an abandoned Knight HiFi kit. Its kind of similar to the Rocky, but with 6V6s. It has an Ampeg inspired preamp so I call it Peggy Knight. (makes my future look so bright)
I have a 6SL7 in V1 and 6SN7 in V2, and a raw control (also something I got from Sluckey) that works great.
