Nice job and an interesting support idea from the top panel rather then the bottom base.

What metal is the chasis plate? Did you cut out for all the mountings? Also where did you get the support studs ? That really looks great. Dale

Great idea. Did you use SS carriage bolts for the legs?

Thanks for the interest in my project.

Base plate is of (5mm = about 3/16 inch) polished aluminium. I made the base plate with holes first, then I assembled the bolts in to the corners. Transformers and sockets then and after all wiring I made the wooden panels.

I liked this way when I invented this. I had a lot of room to make wiring etc. and no worry to break wooden parts. Steel bolts are very stable to support heavy plate and transformers (40 pounds) during building and later on. I had also bolts on the top side during building to secure tubes in testing phase. And you can adjust height of the chassis freely afterwards to keep the device aesthetically balanced.

Bolts are of ordinary galvanized steel. Bought from the nearest ironmonger for a couple of bucks (3$/pound). SS bolts are (here in Finland) a little bit too grey in color compared to aluminium plate.

Very nice! One of the best looking DIY amps I've seen!

May I ask where you got the transformers?
