Mains TX for this and previous Aikido were both custom wound by Shinrock and they are totally silent. 0.7mV hum both channels.

Hi everyone!

My first Tube Amp working at low Voltage of
24Vcc.
The output power is about 2W @ 8 ohm.

I used one PL504 and one 12FQ7 (ECC82/83 are also OK)

Interesting use of the tubes,

When is the stereo version being made?

Where did you get the circuit diagram?

Regards
M. Gregg

The circuit diagram was found on the web, but I modified it quite a lot

I will post it soon.

Hey pilovis, I see you care for audiophile grade parts. Also, feeding that big tube with only 24V is going to make him angry - good for hard rock.
