Jeff and Dennis sure know these low powered 2A3 SET amps and the execution of the power supply.I'm still shocked at how Pat(Banpuku)is driving a pair of ESL63s full range,with a 2A3 SET amp. He got quite a bit a help from Jeff and Dennis and I hear lots of good things about Dennis Fraker.
I remember talking to Jeff a few years back and it's not necessarily how much power you have but it's how well the first watt is delivered to the load.Of course that is where 85% of your sound pressure and musical architecture of your amp comes from,depending on how loud you listen to music.
Fri,did you ever live in the states?

Yep, I think I'd very much like Dennis - seems like a genuine person willing to look at a challenges and their solutions in unique ways.
Cheers,

I still am quite amazed at how well my Quad ESL 63s are driven by the 2A3 amp that Jeff has helped modify. Out of the box from Tube Audio Labs, the 2A3 amp was very good and drove the Quads nicely. Please see the link below for my review of the 2A3.
I have a natural tendency to want to learn and explore, so I started tweaking the amp. Thank you to many who have chimed in on this regards, especially Jeff and Mikey. I have made a few significant changes and I believe most importantly, the power supply changes recommended by Jeff. These changes brought a whole new level of dynamics and transients that I had yet to hear from any amplifier. I now can play music at lower listening levels and it still sounds dynamic and lifelike.
Thanks to all on Audio Asylum who have responded to my posts and helped me learn a bit about DIY tube amplifiers. Great eduction. Very fun and much appreciated.

"Favorite Rooms"
Read first three paragraphs.
Gordon Rankin gets a rave, likely deserved, we couldn't get away to hear it, wish I had. Then read third paragraph about Dennis' room, etc.
For anyone on this Forum's information : the red amps' Hammond Power Transformers ( very likely ) had modified lead ins, the chokes in his LSES supply were ALL Non Critical in Henries, all 11 Ohms or less, and there was tastefully ( and expensive ) multiple film bypassing ARTFULLY done, where Dennis determined it was needed, to get the sound and bandwidth he wanted. He demoed with JJ 2A3-40s, ( which I liked ) not his EML mesh plate 2A3s.

I had the good fortune to visit Jeff Vaughn's place a few years ago (before the plasma speakers) and the pairing of his speakers, then, with Wavelength SETs was so, very good sounding to my ears. That has also been my experience at previous RMAF events.
Why the Hell would you think it's OK to email me uninvited when the moderators have repeatedly told you not to respond to my posts? I couldn't care less about the fiction writers at Stereophile. Don't do it again, and don't respond to this post, either.
