The wax capacitor is a prime suspect(I regard them as 'change on sight' components) especially in a two-stage circuit where it couples the anode of the first stage to the control grid of the next (output) stage. Other possible causes are the metal rectifier, if one is used, and the reservoir & Smoothing capacitors (in the metal can). What valves are used UY85/UL84? (This is the typical 'one-valve'- so called because the UY85 is a rectifier)
