Attached schematic. Basic ST-70 iron, variant of El Cheapo, but I wanted a little additional gain, hence the input stage. Don't want gobs of feedback, just enough to give a decent damping factor. Amp will be 6dB HP filtered at about 60Hz.
So which tube is recommended for the gain stage? Tubes I have on hand are few: 6SN7, 12AT7, 6N6P, 7119. This amp is not worth the 7119, IMO, and the SN7 might be considered a waste of a good tube given the ST-70 iron, but they are easy to get. 6N6P is a nice little tube, but likes a lot of current/lower voltages. Tough to get from my 420V B+.
Any dual octal or 9 pin triodes are welcome. No AX7 or AU7 please. THX.
