Thanks for the information Shannon,
I am still waiting for my transformers to arrive, so in the meantime, I am looking at pre-amp buffer, and gain stage schematics, and was wondering if I would need one. I believe my DAC has the usual consumer line level of ~ 0.5 Vpk (-10db). My speakers are rated 93dB / W (1m), so that half volt, should make some music, but I guess I should add a liitle gain ahead of the G.S.G, if I want to get all the volume I can (but will probably never need). The DAC would likely sound better at half output anyway.
If it is not making X-rays, your B+ is too low.
