Here is my 45 build.

I used the Craigtone Korneff circuit

It’s a bit high density - a lot Iron jammed into a small chassis. Had to take a lot of care with layout so as to avoid noise. It’s dead quiet and sounds amazing!

Using a Winged-C 5U4G rectifier. Output tubes are from the late 30’s/early 40’s. RCA Victors. 6SN7 is an RCA from early 50’s. The vintage tubes were bought from Andy and Vintage Tube Services.
