Integrated model. working on a headphone version . . .

It appears that the problem in understanding arises form the difference between amplifier output impedance and the actual matching impedance. For example, a tube amplifier can have a tap for 8 ohms, but a output impedance of - say 1 ohm. The 8 ohms comes into play when you match the speaker or...

Power supply is CRCLC, with the last 2 stages of filtering split up to one section per channel. This then forming a semi dual mono PSU setup. REctification is either 5U4G or 5AR4.

All amplifiers start off with a 2 mm thick copper grounding plane prior to the point to point construction. This way ensure the absolute lowest noise and hum possible.

This is the 2 Channel full spec version.

Good day to followers and friends. I am the manufacturer of these amplifiers. I shall be posting some pictures and information regarding these headphone amplifiers as I go along.

I've also been lurking around the forum for a while. Thank you for the opportunity to engage here.
