Philco 40-155
#8

Thank you for patiently writing a thorough answer.

The radio indeed did come with a 6J7 instead of a 7J7, the tube socket is riveted in. Would performance increase rewiring the radio with a 7J7? Listed tubes are 1232 although it has a 7G7, 6K7, 7B7, 7A6, 7C6, 2-41's and a 84.

I replaced the 3900 ohm resistor with a 4.7K, sounds like I should get the value back to 3900 ohms.
