In Reply to: Mmm have some 7N7's allready...now just the ECC99 posted by Bas Horneman on November 21, 2002 at 14:12:58:
Hang on there - the ECC99 is a 12a*7 base - heaters to 9 and 4+5. 6N1P is heaters to 4 and 5. I run the ECC99 at a lower voltage and current, and direct coupled from the first stage. Standard long tailed pair type circuit.
