Tubes light up - no sound. Tracked it down to a very large wire round resistor under a cage. It's clearly open and tests open. Issue is I don't know the value. As well, does anyone have a schematic for this obscure Polish set? Would love to get it back to working order, it's in amazing condition.

Yah,

If it is the B+ filter resistor, schematic says it's 1k at 8 watts...
