[NLRS] Looking for feedthroughs

[Dr. Gerald N. Johnson]

What size are they? Kuhne doesn't admit on line what they are. The 
picture of the typical transverter does show them but at too small a 
scale to tell the size. The Italian source he says to go to for parts 
has them in three thread sizes, 3mm (essentially 1/8th inch), US 8-32 
thread and 6MM (6.45mm is 1/4" a size we've used for eons).

Starting a search at Digi-Key, I found their number 410-1156-ND fits a 
4-40 hole, smaller than 3mm rated for a 10 amps, 300 volts 1000 pf. 
$7.11 in stock. Might need washers to keep it from falling through a 
1/4" hole.

I would guess you need 470 to 1000 pf, not critical.

One surplus store down town or the consignment center might have 
something adaptable (e.g. by opening up the hole with a drill).
