Grandfather Clock Chassis 70 "no volume" Help
#2

Hi John

Have you checked voltage readings? Are the coils OK? The primaries of the coils are known to go bad frequently.

How about that large multi-tapped resistor? Sections of these resistors can go bad.

Make sure your resistors are within 20% tolerance, change as needed. Also check the RF choke at the plate of the Type 24 2nd detector tube for continuity. Make sure none of the mica capacitors have shorted.
