Jim - I recently had the failure of a 170pF doorknob in an Ameritron AL-1500 160M padding section. Replacements readily available: http://www.ameritron.com/Product.php?productid=290-0170-7
I believe Surplus Sales of Nebraska and RF Parts also sell the HEC doorknobs. 170pF sure seems to be a "sweet spot" value from its wide use and availability.
