[Amps] SB 200 Input Wafer Switch

[Ken Claerbout]

That's exactly what's happening, the selected band is ever so slightly
making contact, shorting it out like the unused portions.  A gentle
tweak of the bandswitch opens it.  I didn't see a way to adjust that,
but I'll have a look now.
Thanks!

The shaft from the main switch can be rotated by loosening the main nut on the front panel, you have to align the opening on either end of the switch rotor so that the center of the opening is in the center of the free switch contact.  If the opening is off the error is compounded and some bands might be shorting.  Your moving the band switch might be breaking the short.  Make sure you check that before you go nuts changing the wager.
