Howdy...

I like Line Array speakers, VFET amplifiers, Negative Phase 2nd Order Harmonics, and Dogs - not necessarily in that order.   :green:

Yep, I love all of that nasty distortion. :)

I had a SIT-3 for a while and am really enjoying the F8 I have.

The F8 is a great amp.

I don’t know the exact temp. They run warm but nothing especially notable, IME.

I have a bunch of amps / Pass amps. I have not had them fired up in a little while as I’ve been listening to the F8. I can try to remember to point an infrared thermometer at them the next time I have them running.

The F8 is a great amp.

A reboot of the F3J i believe. That amp far exceeded the it’s 300 unit production run. A fave of the Far East.
