very glad to see your masterpieces shown on this site. You are too miserly to display your amp. colletion on NiuShiFu, though nearly every old man there knows that you are hiding a goldmine. When will your 813 venture be finished? I am looking forward to a surprise. Here is my mahine which is not much satisfactory and I use it as a testing one. With OPT input resistance as 2.5K, it can be powered by a couple of Shuguang 6P3PJ, the cheap equivelant of 6L6, or four 6P6P, the equivalent of 6V6GT, two each channel. The driver is 6N2, a tubel close to 12AX7. Well, the sound effect is, how to say, just so so, perhaps for the quality of OPT, with high distortion in the high frequency band. This is what I ever mentioned to you.

Hi WD40,

Does your 813 amp sound good? And do you have a schematic?

Regards,
Bas
