89s doing strange things; now if only you can get it to wash windows then you could forgive the other sins.
Dan - so, you mentioned solder points but are there any riveted terminal strips or tube sockets? When I was restoring a 1935 chassis, out of curiosity, I measured resistance in all the riveted chassis "ground" points expecting to see zero ohms. Several went from 500k to 2meg. One, on the grid leak to a tube, just floated around. And those dog bone resistor wires can get flaky and disconnect from the resistor body after heating up. Maybe go tap each one with a stick, staying away from the chassis. These intermittent issues are nightmares.
