Recently my 2A3 SET amp passed away  and I decided to build a replacement..  The design is taken from TubeCad.  Currently operating around 4w @ 8 ohms & 2w @ 4ohms.   Gain is 6db. To be honest when I started laying out the PCB I didn’t have high hopes it would function.  The design appears to good to be true.  A serious design flaw would appear upon power-up..  Nope.. It works.  The design is pure genius    Please see attached.   Waiting on the cases and an usb differential scope. Hopefully I will post a FFT very soon since a single ended measurement is a no ‘go’ with the differential output (aka phase splitter)
