According to the pinout, the break is on the second grid of the ECC82
I am still thinking the fault resides in the amplifier though. I'm just not sure if a poor connection on the ECC82 oscillator would cause lack of volume an no erase. Please correct me if i'm wrong.

Looks like heat damage to the cable insulation from soldering iron, so should be OK. If the ECC 82 is just for the oscillator, then even if it had a fault would not expect it to affect playback volume.
Have you checked the EZ 80 HT voltage yet ? If OK then check the valve electrode voltages and see how they compare to schematic values, mainly anode, cathode and G2. Also should not expect to see much if any +ve DC voltage at the Control grids G1, unless previous valve anode to grid coupling capacitor is passing DC/leaking.
