Both sides are set up to work in. I used 12au7 tubes and a b+ voltage of about 150v. Web headphone amplifier 2021 started in the 2021.

Web Bear In Mind The 12Au7 (Ecc82) / Irf510 Headphone Amp Has Its Output Inverted, Fixing This By A New Schematic This May Result In Better Sound Quality.

It should not be hard to make something along those lines with a 12au7. The power supply is rather simple and straightforward, a 12v sla battery. Looking at the schematic closer recently, as i've started to gather parts, i've.

Further More With The Orignal 470Uf Cap You Would Not Be Driving Any 8 Ohms, Because You Can Calculate The Cut Off Freq At 8 Ohms, This Is Way Above 20Hz.

Web the 6cg7 is the starting point and the input sound is amplified by 25db and then the 12au7 gives you an extra amplification of 30%. Web web there are not many freely available tube headphone amp schematics using the 12ax7 with the exception of a few electrostatic amps where gain of 1 trilion is. Web #1 i'm trying to design a headphone amp intended for relatively higher impedance headphones, 200 ohms at least, so i don't think transformer coupling should.
