Default My first tube amp: 6C33C

This is my first diy tube amp and i took some pictures on it. The chassie is made by me in 3mm steel with 10mm alu front. And the hood is made in 2mm steel. It will get black paint on the steel and the front gets natural brushed aluminium.
The tubes are 8 x 6C33C, 2 x ecc82 and 4 x 6n6.

Moore to come.

Wow. I wish I knew how, and had the tools, to do metal work like that.

So far very nice.

Yes, it's a Otl. Schematic is a modified Cuffolli 8:2 something. The transformators is from Tramo ETV. Binding posts from Supra and rca from Neutrik.
I think the chassie will be good with some work. Some moore holes, sanding, paint, feets and tubes.

Really nice looking chassis.
Are the 6C33C output tubes going to be in parallel, or in an H bridge configuration?

The 6c33c tubes will be in parallel. I only have the schematic on white paper, but i can scan it on work. Some more pictures after some drilling and socket mounting.

not from personal experience but i've read everywhere that you should leave a gap from top plate to sockets, about 1 cm to help cooling the sockets so to have longer life of tubes ... anyway great work!
please share schematics once you're done!
