Re: Modern Class A
Thanks guys, this is just as I suspected. I had read this in a couple discriptions of the "new guru" amps, and a factory tech. I did not see how the operation curves and plate dissipation numbers could have magically changed. What I have encountered in these amps is usually high B+ voltages (480v) a...

s2 amp
BT123, The preamp looks like the typical Fender style found in the non-reverb models like the Deluxe.

6AK6 push pull output transformers
Thank you BT125,
A couple shots of the transformers would be nice. If you could make note of the transformer numbers that would be way cool, and much appreciated.

6AK6 push-pull output transformers
I'm working on a 6AK6 push-pull project, and I am looking for suggestions on output transformers. I believe s2 used a Mercury, and I have found no info on the Dynotweed OT. I am also seeing 5k to 20k being used. What have you had luck with?
