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.

Here is a picture that shows the bandswitch contacts:
<http://www.qsl.net/k2vco/4CX1000A/Chassis.jpg>
The fixed contacts are about 3/8" in diameter. The rotor is made of
several leaves, and makes contact across the whole width of the fixed
contacts. There is plenty of room between the contacts. The insulation is
glazed ceramic. In my opinion, this bandswitch is much more serious than
the one whose burned contacts I replaced in an Alpha 86, and way better
than the ones you find in Ameritron amps.
What exactly is wrong with it?
