Hello
I am in need of a Vernier Tuning Variable Capacitor for a HQ-170,
Hammarlund
part # K42040-2, mine is slipping and not tunable, I also need a clock
knob
Any sources for the above parts new or used?
=============================
Dan:

Have you tried cleaning the capacitor drive mechanism? I use Ronsonol
lighter fluid to de-grease dial drives and it works well. Those
planetary mechanisms should be grease-free to work well. A knob from
a cheap baklite clock radio will fit the HQ-170 clock.

Best Regards,
