In Reply to: RE: OTL amps rule! posted by Mike Mount on June 26, 2014 at 18:07:18
Has anyone heard Tim Mellow's 6C33 OTL? It looks to be one of the simplest OTL circuits to try to build, so I am thinking about trying it out. This will be my first OTL...

Yes, I have built one, and it has been my main amplifier for daily use for a couple of years now. It has never given me any trouble, and the performance is very good.

Have you compared its sound to any other OTL amps? I know Transcendent Sound and Atma-Sphere have their followers, and some of their circuits are reasonable to build. Maybe the sound would be cleaner using several parallel tubes instead of just one pair of 6C33C?
"Have you compared its sound to any other OTL amps?"
I've built another totem-pole OTL using two 6C33Cs, designed by Hans Beijner, and a circlotron using four EL509s, by Alan Kimmel. Also, a totem-pole based on an old design by Dickie and Macovski, using four 6082s.
I'm not very good at hearing differences between amplifiers; I seriously doubt that I could reliably distinguish them apart under double-blind conditions. (Or indeed, any amplifier that is not suffering from some gross defect!) Of course when one knows what one is listening to, hearing differences is easy.
Anyway, I can certainly say that the sound is excellent, and stands up well against anything else I have heard. I suppose in general tube OTLs could be expected to sound more like solid-state amplifiers than tube amplifiers with transformers, simply because they lack the colourations that could be introduced by the output transformers.
