Increasing the class-a ceiling always has a good effect on measured THD upto a volume level. But I am not 100% sure if that will be perceptible in a listening test, with Rev2 even less so.

I'm glad you've built it. Some pics would be great addition. BTW, why not update the thread on the other forum?

Rajesh, I never could get rid of the cross channel hum in the F5T fully. It's very faint now, but it's there. Not one of my better efforts. It works though, and I play it sometimes. I suspect that the hum is robbing it of some of its musical character.

This one, on the other hand, i like... a lot.
