New to this forum but not to audio or on-line forums. Been a fan of high fidelity since the early 70's. Introduced to tube amplification 20 years ago [Dynaco st-70 mk II] and employed valve amplification ever since. After using some very fine push-pull amps I fell in love with low-powered SET amps, coupled with my preferred output tube, the 45. Got my feet wet in computer audio last year. Looking forward to adding another forum to embrace our shared passion.
