Product Page: SA-22 Single Ended HiFi Tube Amplifier
Have been selling tube amps and kits from other suppliers for about 1 year, now we proudly announce the first own design: SA-22 SE hifi tube amplifier. As some of you suggested before, we grouped an amplifier designer team. The leader is Zhang sifu, a 53 year old guru of tube gears. He has 26 years experience of tube amplifier and transformer design.
SA-22 use 6J8P as preamplifier and EL34 as power stage. It's nothing related to EL34 kit selling in our store. SA-22 has new design, all hifi components, and most important of all a pair of good transformers which were also manufactured by us.
We prepared several options for this amp. You can upgrade the transformers to our best Optimus series. Transformer enclosures and 24 positions stepper potentiometer is also available as option.
RA-22 is now available in our store, price is only $282, charges only $50 for worldwide air+ground shipping, no need to wait for 3 months any more🙂

Hi Malibujeff, the sound is even nicer with the Optimus series transformer. We'll begin to sell those transformers very soon.
Inside view as some of you reqired

What is output transformer impedance?
Do you have schematic to post?
What is difference in output transformer choices?
Thanks!

Nothing special for the schematic.
The impedance of OPT is 3.5K. The transformer make huge difference. Standard option use Starfire series transformer build with normal M6 siliconray steel, machine wired. Optimus series transformer use high quality New Japanese Steel high silicon steel, 100% manual made, special wiring method makes it has very low inductance leakage and capactiance. It has far better performance at frequency lower than 100Hz and above 10KHz.
