I am having difficulty getting the 6 MHz coil slug adjusted for the K1 SW band. 12 MHz trimmer cap adjusts just fine. But the 6 MHz slug can be pulled out of the coil but the oscillator is still running too low. I have cleaned this coil of all dirt and contaminants.
Are theses coil forms or wire insulation subject to deterioration? I have disassembled and cleaned the Oscillator section and switches a few times. Insured there were no visible damages to the oscillator coil. I changed the oscillator 50 pf (was 62pf) grid capacitor and the G2 to cathode 500pf (was 637 pf) capacitor.
I even tried to align the SW at 12 MHz minus IF but the trimmers did not cover that range.
I am open to any suggestion.
