Actually I think the schematic is wrong, because in the radio itself both IF cans go to only ONE SIDE of R11, and I didn't touch that wiring except to replace the old dry rotted wire from the 1st IF can and I just wired that wire back to where it was previously, and I didn't touch the wiring to the 2nd IF Transformer because the wiring was fine in it.

Have you tried Deoxit'ing the switch yet?

Yes I have, 3 times and it hasn't made a difference, if anything its made it worse.

To jumper the switch, just trace the wiring. Trace it from where the signal wire exits the 2nd IF can and goes to the switch. And trace from C11 to the switch. Put the jumper across the appropriate two lugs.
If perchance you don't plan on using the phono, just leave the jumper in place. |

I think it is definitely the switch because I'm not getting anything out of radio when I touch the Grid Cap of the 6F5G Audio Amp tube unless I jiggle the switch several times, and even then the hum from touching the grid cap of the 6F5G tube goes away after awhile. |

Its just a standard 6 Lug SPDT Switch. In fact here it is on Mouser. https://www.mouser.com/ProductDetail...6%2FVdLw%3D%3D |

Dude, I gotta apologize. Been giving you bad info. Come to find the switching is done on the downstream side of C11, not on the upstream as in previous sketch.
Thus to jumper the switch, the wires you would trace would be: 1.) from the top lug of volume control to the switch. 2.) from the downstream side of C11 to the switch. Jumper would go on the appropriate two lugs of the switch. Damn, sorry for the screwup |

Turns out there's an obscure little subnote to the main schematic, showing the radio/phono switching diagram. It's difficult to decipher, but shows the switch as DPDT (double pole/double throw), with the second section switching B+ on/off to the mixer stage.
I would seriously de-consider replacing the switch as that could turn into a real can of worms. |

Right now, can you put a record on and play it without any intermittency when you wiggle the switch?

It seems like the radio from h*ll. Its hard to believe that you had so much grief with it. You should replace the switch with a decent toggle switch, mounted on the back of the chassis. Easy to get at a bigger hardware store.

I don't know as I currently don't have the record player hooked up right now because I'm trying to fix the drawer glides because the original drawer glides were bad.

The switch on the back won't look as complete as having the switch in the front like it originally had. I think I found a switch over at mouser that might work in place of the original. |
