The problem might not be the switch.  If the contacts are in good condition and 
you cleaned the switch the problem might be alignment.  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.

I have an SB-200 I restored for a friend.  It had a fried bandswitch.
I installed the Harbach mods also.  It works great except for the
input wafer switch, which is a little flaky.  On a couple of bands,
the transceiver see's a high VSWR, which can be resolved by nudging
the bandswitch a little further clockwise.

I wouldn't mind replacing that switch.  It's a little beat up.  But I
don't see any for sale.  Before I start searching for a suitable
replacement, I thought I would see if anyone knows where I might be
able to get a replacement?
