I stayed up late and gave the sound IF and good going over. Right away I noticed a 1K resistor with a crack that measured about 300 ohms. The one to the right of it measured 1,300. Both got replaced.


Next came the mica caps. 3/5 were bad - a 10pF, 27 pF and 47pF. By 'bad' I mean they were showing leakage at less than 200 volts (all are rated for 500) and I couldn't get a capacitance reading. Hopefully, replacing these will have a positive impact on the sound tuning.
