Radioroslyn - I swapped out the 78 tube and there was SOME improvement. I can pass a 460 KC cycle through the set, but it is VERY weak. The tone is not clear, and has much static. I thought that I might have better luck by connecting to the 6A7 cap, as per the Rider instructions. There was NO tone after that and much electronic buzzing, even with the volume reduced. The tube tests okay. Any input would be appreciated.
