I'm getting weak, distorted output from a Philco 40-120C that I'm restoring. I traced the location of the distortion to the plate on the 35A5 tube. I've checked the tube's grid and plate voltages, and they're a bit high (by about 10%-15%) but not too bad. I've done the obvious things (e.g., replaced caps, resistors, tested the tube, etc.). Any advice?
