[Amps] Johnson 6N2 Thunderbolt switch

[n1rj@pivot.net (Roger D. Johnson)]

 Having re-read my first post, I realized that some clarification
is in order. The switch wafer is actually 1 5/16" across. I'm
not sure this matches the original switch. It looks like the
switch had been replaced by a Rube Goldberg arrangement of two
wafers back to back. All the photos and diagrams I can find show
just a single wafer.
