More working tonight. Subbed in interstage transformer between 1st audio and 2nd audio. Don't have a high enough impedence p-p output transformer, so could only use 1/2 of the output section (which is sort of OK, since I don't yet have the other tube, either). I'm using a SE transformer designed for 3V4 output, the the match is at least, if not in the same ballpark, at least in the same league. Given all of this, I'm getting reasonable output, with pretty good quality audio. I'm sure it will be better when I can locate an appropriate output transformer and the other 112A comes in.
