Hi,

Here is the SCH of this Board that you see above.
I didn't buy any part yet, but I'm waiting for the board quote.
In fact I'm looking for chassis and cases for my amp. I'm very demanding with the case, especially for a project with this price.

Hi to All,

I'm designing a KT-88 Ultralinear amplifier using the idea of Satoru Kobayashi 2002.
The pre amplifiers is a solid state using a TL-72 with gain 10 and the second stage i have the superb DRV134 Burr-brown (Low distortion: 0.0005% @ 1KHz) which is a differential output amplifier.
Following comes the 6N1P svetlana and the EI 12BH7AEG direct coupled and the last stage with KT-88.
The most important part is that it's all in one, I mean, all in one board. I integrated the high voltage power supply regulator and the low voltage for the op-amps in the board eliminating wires around.
I've been working in this board for more than 3 months and creating BOM, calculation an so one. So far the project is around U$ 1266,00 including all parts, not board, and transformers plus the tubes.

Attached you can see the print-screen of the board. I didn't send to production yet, and i plan to go slowly in this project due the cost mostly...
