PHILCO 37-660
#18

Arran and Morzh thanks so much for the help. While I could not get in the tangle of parts and wires to verify the plate wiring of the 6F6's , I did pull info for pin numbers of the 6J5. On it, pin 4 and 6 are idle. I then looked inside at that socket that is labeled as the 6J5G on the tube label diagram in the cabinet and it matches! Sooo, I will make sure the tubes are installed per the cabinet diagram this time. By the way, the label looks like it says code 121. Also Service Bulletin 257 states that the correct rectifier should be 5X4G as the label in my cabinet shows. I have ordered a 6J5g replacement for the broken tube--they are not cheap! Thanks again to all for the help, John
