Need some direction on a grrreat little Philco PT-30. I changed out all capacitors, dialetric caps, and some worn looking resistors. I checked all the tubes and all test good. I used my meter to check for ground on the outside tube shields to chassi on the three of the five that are wired for it, all good. The audio sounds badly garbled, like a motor boat. The volume does goes up and down. Loud and strong. The lamp lights up bright when I turn it on then goes to a real low dim. I know this is normal but it is real dim when it finaly settles. New power cord also. SO what next? Any direction is helpfull. Can it still be a bad tube? I feel it is a ground issue, is there a way of checking each tube base? IF so which tube first? I get channels in fine. Is there a trick I am missing? Will send pics if interested and help. thank you for your help. Napi
