Power amplifier with 25 watts of power all in pure class A at 4 ohm and 20 watts always in class A at 8ohm.

For all the people who don’t know tube amplifiers and are used to the 100 watt minimum, written on all Japanese amplifiers, perhaps they can’t understand, but I assure you that perhaps these 25 watts sound louder than the 100 watts we find in the Japanese amps.

LThe amplifier works in pure class A and uses, in each of the two power sections, two 6L6 beam tetrodes and also the 5881. The transformer is a toroidal built to Graaf specifications.

The bias is automatically adjusted with a particular circuit, therefore it remains stable even in the event of wear of the tubes and replacement of the same
