Thanks John,
Like a lot of posters here, I bought some 5AR8 tubes a couple of years ago meaning to give it a go but never got around to it - now's the time. I'm planning on building a Zeus amp (Susan Parker's design) & I was agonising over the best way to feed a balanced signal into a 600ohm input trafo but now this may well allow me to dipense with the input trafo & use this BDT preamp as both vol control & phase splitter.

Waht do you think - is this feasible? How would I bias the Mosfets if I substituted the BDT preamp in place of the I/P trafo. Sorry for the questions but as you can see I'm no Ee & struggle with the simplest of things!
