Ok.

Now, I've got the permission from Mr. Lazaroiu and this is the final schematic.
As dual opamp, I used, like I wrote, LF353 instead of the original from schematic, LT1058.
It result a good sound and enough atac for GU29. Of course, it's my personal opinion obtained from the amplifier sound.

Good luck and try the schematic, it worth! It sound and work great!

Congratulations on this project!
I recommend another schematic with excellent performance that can be easily framed in Class HI-FI.
Only 4 Double vacuum tubes 2XE92CC and 2xGU29 achieve an excellent amplifier all tube

Of the schematics I have seen for this tube the first one posted appeals the most.

Nice build. I'm glad you covered the open frame trannies. Good work, it looks smart.

Hello, I would like to know how the amplifier works after years, were any improvements / modifications made?
Best regards, Piotr.
