In Reply to: One point--the Atma-Sphere OTL amps use only one pair of (normal-value) coupling caps... posted by jeffreybehr on July 25, 2006 at 16:40:43:
>> and NO coupling transformers in the entire ampI did with Lundahl 1660 (with either single-stage and two-stage drivers); single stage to IT definitely beats the 'normal' cascoded front end with generic resistors, paper caps and crappy soviet 6n8s (I'm talking about a DIY, not commercial amp). Some 'upper air' was probably lost, but otherwise it was cleaner. Plus the reduction of driver power supply.
