Jon - I liked and enjoyed your pictures, your amps look promising to say the least, based on the manufacturing process and parts involved. parabiens!

HI flex007 thank you

Hi, after a long period of development, finally the element to the power amplifier. The preamplifier, 100% discreet and with a bandwidth DC to 1.2 MHz,-3dB.

Careful attention was paid on the circuit board and the choice of components for this to be possible, especially semiconductors and resistors of 0.1% 15ppm at critical points . Do not use capacitors in the signal path and no servo circuit (this usually affect low frequencies).

Nice ! Love it ! I just bought several ECF20N20 ( TO-3 case ) for my own designed class A amp , still waiting for the parts to arrive though.
