Thanks.

Yeah, i think the 6at6 is biased wrong. The 3.3k is just from a schematic i found. 1k would make more sence.

I havnt mesured the voltage because i dont have anythgin to do it! My multimeter has died on me again! I hate them. Even the not-so-cheap ones die after a few months. I need an avo.

Yeah, valves are pretty new to me. I'm too young to have seen them in use, and the only thing i know about them is what i lernt form audio stuff. Whereas solid state is abit more familiar.

The switch mode psu ismore sucessfull than i thought. It's pretty simple, yet effective. Not a normal combination.

And the heaters seem to run fine off only 6v. I'm using a big lantern cell rated at 11Ah. Not sure how long it'll last, but cirtenly worth £2 i reckon.

I need to get hold of a really small audio o/p valve like an el85. I think it's charectaristics would suit this better.
