Default Pete Millet's Uniamp

Hey Anyone,

I'm working on building a Pete Millet Uniamp using 2A3 outputs. The input is, I think, balanced and uses an input transformer. I'm building this amp for a friend that is wild about 78's. So it will be a mono amp driven by a stereo preamp. I was going to use a pair of resistors in a 'summing circuit' but there might be a better way?

Instead of the very expensive shielding of the Sowter or Lundahl input transformer I plan to use an Edcor WSM 10k/10k as the input transformer and then shield it myself.

Could I just connect the stereo inputs to either end of the primary of the transformer?

I found the solution. Edcor WSM 6400. Stereo to mono input, either balanced or not for the output.
