Just finished building this amp

[cytovette]

This is a 3wpc amp using Russian 6E5P tubes in a push pull circuit. The circuit was designed by Doug de Young at Bugamps.com, I designed and built the enclosure and figured out the layout. I am driving Klipsch La Scalas and driving the amp with an Adcom GTP-500ii preamp. I made a video playing a record if anyone is interested. It sounds really good, of course my phone didn't do a great job recording.

Hell yeah, the 6E5P is a rather interesting little valve. How hot does that PSU fet get?

I have the FET on a piece of aluminum 1/4"" thick and 2" x 2.5" and that bolted to the chassis. You can see the bolt heads on the top. It gets warm but not hot, I can lay my hand on the chassis where it is heatsinked for as long as I want with no discomfort. On my first iteration of the power supply board I just used a small heatsink and it got way too hot, so I sinked it with the aluminum block to the chassis.

The input and output transformers came from Aliexpress.
