Anyone using modern carbon >film< resistors instead of carbon composition resistors to replace the 15 ohm cathode resistors in the T-4XC PA? While I'd never use metal film there (save those for PS use) I'm guessing the inductance of carbon film is low enough to be OK? I know you can still get carbon composition from some sources, Mouser included, but I've already got plenty of carbon film on hand. Dan WB4GRA
