Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Guys
Even those the trannies are a different manufacturer,everything measures identical right down the voltage out of the power trans to the audio response of both amps at full power and at 1 watt.
When I finished doing both amps,(Mcshaning I call it because of the parts layout,everything was perfect and the freq and power sweep on the amps were identical.I couldnt belive it.I did however add more decoupling capacitance and the amps respond very well to that.
The circuit is not a voltage doubler as I thought.Its two filter caps hooked in series and the place where they join is where they tap the voltage source for the 6sn7s.There 525v out of the power trans but at first glance it looks like a doubler..Also the amps have a choke input filter and thats one of the reasons I have pretty stable regulation.
Maybe Jim can put together a kit for these becuase they are nice amps.
