Doesn't the wire from terminal 3 go to ground through cap 35 or is my schematic reading inexperience on full display here?
OK that's the schematic I have.
OK I was doing something stupid. The wire from terminal 3 is fine...it reads infinite resistance to ground. The wire from BC resistor terminal 4 is the same readings as before...90.4k ohms with the speaker unplugged...3200 ohms with the speaker plugged in.
Pics show these 2 readings, the speaker socket and the general area around the speaker socket. All tubes are out. In the last pic, that small black box attachment is for a 1/4" jack input for Bluetooth and similar input. Pretty sure it's not an issue. Radio and it worked fine before.
Chris, when you recapped the chassis, did you replace the caps in the tone control?
No I did not...I just sprayed contact cleaner on the 3 tabs and worked the controls
OK, with the speaker plugged in, repeat the resistance check on wire 4. This time, turn the tone control to each position while checking.
Steve...it is 3200 ohms in all 3 positions on the tone control
The tone control should have four positions. When the control is fully counter clock-wise you still get 32K?
Yes 3.2k...3200 ohms...not 32k
Yes, I meant 3.2K. Take resistance measurements on all speaker plug terminals first with the speaker plugged in and again with the speaker unplugged.
Steve
OK starting on speaker socket that is connected to BC terminal 4 and going clockwise.
Speaker plugged in:
1. 3200 ohms
2. Infinity
3. 98k ohms
4. 20 ohms
Speaker unplugged:
1. 90.6k ohms
2. Infinity
3. Infinity
4. 22 ohms
The B+ line (speaker socket terminal 4) is shorted. You will need to trace that line all the way through.
Steve
Will do...thanks so much Steve...I'll get back to you. It's socket 4, the one that's reading 20 ohms plugged or unplugged correct?
Yes, the one reads 20 ohms
