Help deciding on a low cost 15-20 watt triode push-pull amplifier design.

Hi. Pregnant pause at the moment. Have order some, ehem, Lundahl 1679s. Not really cheep anymore, but I sold some stuff and had a bit of extra cash. Also they are relatively more huge than I had allowed for in the original design, so have stopped building as I will work out where everything will fit, when they turn up... Hope they turn up. Was supposed to be 2 weeks, but nothing as yet.
I am building the the circuit in post 72, as it is a little un usual with a transformer input, and promises low distortion. I have enjoyed all the other circuits, and quite like the idea of the non symmetric triode amp, and introduced me to some other nice valves, like the CV6040, which is a 12E1 in a smaller bottle.

Nice. Looking forward to hearing how it turns out.
