Just noticed your post. I actually built this amp about 2yrs ago. Very nice sounding with EH EL34's. Smooth and sweet. Sweetest in triode mode, but a bit more authoritative in ultra-linear. I had it mated with a Bottlehead Foreplay and Vandersteen 1C's and was really happy with the combo. All components are high quality. Iron is very heavy. Overall a really nice amp, especially for the price.
