F2a11 or EL12
Push-Pull monoblocks ,
with TUBE RECTIFIER CIRCUIT
this amp is a V69 killer I had compared with telefunken V69b, this f2a11 PushPull is much better
2x40watts
THE F2a11 IS ONE OF THE BEST TUBE in the world
made by SIEMENS in the golden tube ages (10.000 hours lifetime), and was used in a lot of amps,
KLANGFILM, SIEMENS, TELEFUNKEN, push pull studio amplifiers
My opinion the OLD german AUDIO tubes much better
than new chinese CULT tubes (300B, 211, 845)
The tubeguru.hu is building tube amplifiers
and I prefer the OLD german AUDIO tubes!
For Us the MAIN IMPORTANT IS DEVELOPING+WATCHMAKER HANDBUILD.

here is a feedback from a happy german owner who has a same f2a from me!
"Hello Tubeguru,
sorry, I'm listen with my new amps my music every day
and don't turn on my computer.
I am very happy, it's so good!
First I change only the Poweramps and at this time I know,
I will never hear my Musical Fidelity Nu Vista M3 again.
There is more detail, more dynamic and more stereogram.
I can listen now very silent and I can hear it all exactly.
It is the best Amp I ever heard! Made by LUA or Oktave
it costs proximate 10.000 Euro. The risky busines (I never
heard Your Amps previously) pays well.
Many thanks and best regards"
