Using a Clementine as a line stage
Posted: Tue Sep 17, 2013 9:06 pmI have two clementine boards I want to use as line stages . would use a 6J5GT as the output tube , with 250 or so B+ what should the value of cathode resistor be if I use an UTC A-25 output transformer .

The other option I have is to use a 47K to 68 K plate resistor and parafeed the UTC A-24 transformer with a 5.6 uf cap , have the A-24's and the A-25's so doing one board of each wouldn't be a problem .I have one HA-113 and one LS-50 which have better specs than the A-24's which I would like to use latter if I can find a mate for either of them .
