Thanks again guys, I have this up and running in the system, boy does it have grunt in the low end, much more than I would have expected from a 10 watt amp! One problem I seem to have is the input gain, running my HH Scott 310 preamp down in the low end of the pot I have a bit too much non-linearity between the channels at normal operating values, if I goose it up, the channels balance much better but then I get yelled at to turn it down! Wondering if I substitute a 5751 for the input tube (12AX7) if that is OK as the 5751 is a lower gain and supposedly similar to the 12AX7, what do you think?
