Hi, OTL using , 6J6 for differential input with CCS at common cathod, then 6DJ8 + EL84 to drive 6H13 as ciclotron schema.

@ Winwss : Last ten years, Tawainess have bough a dozens containers of US JAN tubes, as a result now we can easily to buy only military power transformer ( US JAN ), USSR tubes, oil Cap.... but in fact we still have enough for DIY in 30 years more.

Hi viagraless, thanks for that. I'm always blown away by the level of activity and craftsmanship in Vietnam. Also nice to see someone else using the 6J6. BTW, the Russian equiv has lower distortion.

813 mono block

Hi, Mr. Viagraloss,
I think that have something wrong here. There are 805 mono bloc amplifier from Mr. Tuan Anh with 75TH tube driver, not 813 tube.

Dear Mr. Macao,

Thank you very much for your full support, I did download your schematics. This is my big project!
Can I replace the 813 (USA) by FU 13 (China) tubes, 6C4C by 6Pi3C? And is the 5691 same 6H8C tube?

Thank you very much

Best regards,

Hi Thomas,
As soundbrigade comment, you can replace 6C4C by 6B4G or 6A3 but 6C4C is cheapest in all of them, 5691 must be replace by 6SL7 - 6H9C tube type. If you have any idea to change tube in preamplifier or driver stage, please direct contact to Mr. Dztronic.
Best regard.
