Philco 40-180 no tuneing
#10

I’m at whits end can’t understand why this simple circuit won’t oscillate I’ve substituted all caps including tuneing cap & grid leak resistor checked coil resistance and connections, i can make it osc but with almost no tuneing by increasing cap 19a by 150mmf can even disconnect tuneing cap same result. Switches all working normal.removed wax from osc coil checked windings I can’t think of anything else to check. Anyone have any ideas? Push buttons working normal.
