Truetone D-726
#9

I haven't been able to work on this for a few days but I'm back at it. What I have found.

Center tap was tied to the chassis directly.

The cathode of the 42 pin 5 was not tied to the chassis and also had resistor 250 ohm tied to it which put in series with the other 250 ohm resistor so it was a 500 ohm resistor.

The negative of the filter caps was tied to the chassis.
I have corrected these and decided to go pin by pin with a highlighter and have already found another but I'm not sure on this and that is on the 42 Pin 2 Plate has a .005 400v cap between pin 2 and pin 3 and the print shows a .01mf but the cap looks original.
