[Amps] Arco 30 Series Trimmer Cap Nuts

[GaryK9GS]

I would try calling ARCO or one of their distributors.  Maybe also try Max Gaines systems. Maybe RF Parts can help.  Regardless, I would call not email.
If you Google 12-40 panel nuts you can find them too..if this is indeed the correct size.

Hi Jim,
   Those are brass 12-40 panel (thin) nuts.

   I searched for those in vain about a decade ago.

   If you have access to a lathe, you might consider making some starting with 3/8" brass hex stock and a 12-40 tap (rare, but not impossible to find).

 I hope it’s okay if I post an amplifier
 related post on this forum.... :(
 
 
 Does anyone know what type of nut is
 used on an Arco 30 Series ceramic 
 compression trimmer capacitor?
 
 None of the standard (SAE) or metric
 nuts at my local hardware store work.

 Anyone have some? Need about 15 of
 them.
 
 Thanks!
