ericj,
shame about the 12AU6, ah well, can't have everything 
For now, it'd be good to stick with 12AU7 (ECC82) rather than a close equivalent (or otherwise) when building the Stoopid.
I did try some other 12.6Vac valves (ECC series) but the *gain* was way too high. But the main issue was to pick a a valve that's not particularly good ( equals *cheap* and easy to get) yet the datasheet says possibly works at lowish anode volts, then try to compensate for other nasties that introduces. That's why the anode load is a CCS, yup, runeight sorted that.seaside,
this amp is different to other amps we've cooked up in the past as it allows experimentation with valves with a much reduced risk of being thrown across the room if you touch something you shouldn't  Does this mean at last we get you folk to "try a tube" ?
