This photo from Chuck Schwark shows the "official" Philco tool that was used to adjust the trimmers: http://philcoradio.com/phorum/showthread...70#pid1470

Here's a tool I made to get the job done: http://philcoradio.com/phorum/showthread...8#pid52048

And some folks take an old Bic ballpoint, take of the little plug that is on the end opposite the writing point, heat up that end and smush it down on a 1/4" nut to form a tool.

I have a few more left from the batch I made, if you PM or email me your address I'll send one to you.
