[Amps] Building an Amp 101

[Carl]

That switch is an old Radioswitch and has no problem with power or voltage.

All the senior Ameritrons have always used the same Centralab JV-9000 series 
switch (now Electroswitch) as the Alphas except for the 70/77 series which 
was a 86 series Radioswitch. Even the Alpha dual 4CX1000A version uses that 
now Electroswitch model and just paralleled up wafers.

Ive run up to 5KW out thru a single 2 pole wafer wired in parallel in hot 
rodded LK-800's and owners have never had an arcover. Any belief the switch 
is inadequate is smoking funny stuff. Granted some could blow up anything.
