My first tube amp: 6C33C

matsj · 20th January 2011, 06:47 PM

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.

Impressive project. OTL I assume? What schematic are you going to use? Keep us updated!

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?

very nice, could you share schematics please?

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.

excelent work mats!

Trying to do something like you did... not finished yet...

& for fun!

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!

Thanks for the advice about the sockets.
