Two-chassis SET stereo amplifier with separate power supply. 1.5 watts per channel using 45 output tubes and 3.5 wpc using 2A3s. I'm using old stock RCA 6A6s as a driver tube. Here is a ranked list of the output tubes I have tried so far.
1. NOS globe shape Cunningham 45s (CX-345)
2. Sophia Electric 300B 2.5v (a drop-in replacement for 2A3s)
3. NOS RCA globe shape 45s
4. National Union ST shape 45s
5. EML solid plate 45s
6. Sovtek 2A3
