Default Studer 52

Hi

I want to show you a circuit, I found last week in the Studer archive:

The Studer 52

Click the image to open in full size.

Isn't this a very nice circuit?

Carefully selected tubes, DC coupled phase inverter, cathode feedback output transformer.

Not one part to much, fine engineering work.

A little Swiss Quad II?

I don't know, how many of them where produced. I have never seen one of them.

But it could be a very nice project to rebuild, isn't it?

Kind regards
Franz

Thanks Frank for sharing this schematics.

I did not know Studer had produced an amp.

Thorens produced a amp also with EL84.

Yes, it is a very nice circuit. I like the Mullard front end and the cathode feedback configuration. I also like 6BQ5/EL84s very much. I have an amplifier that is very similar to this one but does not use cathode feedback.

Thank you for sharing this schematic with us.

Hi

I can share more info with you: the production datasheet from the output transformer (sorry, written in German):

BTW:

I plan to rebuild this promising circuit. I ordered output transformers specially for this project from www.roehrentechnik.de, from Gerd Reinhoefer. He will produce them following the datasheet, but using a double chamber in M102 format and todays iron quality. It will be a very well sized tranny for this amp. The price will be the same like the production trannies, he is offering!

Should you want the original circuit and the tranny datasheet in PDF, just drop me a mail under firstname dot name at studer dot ch

Kind regards
Franz
