The arcing on the Figure 23 bandswitch photo on my Web site shows that 
arcing took place when the 80m Tune-C padder contacts were open -  
meaning that the amplifier was in in use on another band (20m) when the 
contacts were burned.  Thus, 80m current can not have caused this damage. 
 

Several SB-1000 owners have reported that when a burned Tune-C padder 
switch wafer was replaced, intermittent arcing continued across open 
contacts in the new switch.  The fix was to decrease the VHF gain of the 
3-500Z by decreasing the vhf Q of the vhf parasitic suppressor.  .  

cheers, Hans.  

If you would like to receive a free-sample  vhf parasitic suppressor 
retrofit kit to try in the SB-1000, send me a postal address and I will 
see to it that you receive one.
