I have recapped the bakelite in this stage but I have two more bakelites to do. E-caps done and resistors look good. Coils have be checked and 2 meg resistor put on the IF coil. Any thoughts?
The sensitivity control is crumbling...I think it is a dielectric cover on the adjustment screw, correct???

Time to start to check the voltages around the 6K6. Check pins 3,4,5,& 8. 3and 4 should have 275vdc or so. 5 should be at -15vdc or so. 8 should be at 0.
