Hello Chris,

Enjoy thre sound...

Thank you! Looking forward to it!
It looks fantastic, Chris!
Little question about layout: I see some amps like yours built with transformers in under the PSU PCBs: it is always hum-free a solution like that or there's the risk of EMI? Thanks
So far it’s dead silent. I’m not really qualified to answer the EMI question, but I did my best to keep anything that radiates away from anything that carries signal. Antek does make a shield that drops over the top of it that I left room for if it was needed. One person suggested that the leads exit the transformers toward the front and rear of the case. That is the only thing that I tried to keep straight.
That sad, I did hook up my old preamp to it with a bad RCA cord/connection about 4-5m away and it was a hum monster! Scared me! But good cables to a newer device right next to it with a 1m cable was perfectly quiet. While likely EMI related, it was more because of a poor cable connection.
This is my latest creation, a 20W, positive current feedback amplifier in a HiFi2000 / Modushop Mini Dissipante enclosure.
Dedicated PSU for both channels.
1,2 Amps / Lateral Mosfet make the amp pretty hot.

Fugly!
M2X build
I built the power supply on the base plate before assembling the chassis.. If you use the spacers suggested by 6l6 between the bottom plate and the heat sink bracket there is just enough room to get to the heat sink mounting screws

heatsink brackets is first thing you need to screw on, not last
and - saying that all the time, base plate lip goes up, not down
then even 8mm risers are enough, to route mains cable bellow

Hello out there,
I finished my 6-24 -active-crossover.
Listening to it with some other Papa Pass-toys....
Have a nice weekend

I have a that fat grin on the face, that I will need a iron to smooth it....
