[Boatanchors] Need SB-220 Bandswitch

[Mike McCarthy, W1NR]

I have had epoxy melt, catch fire and explode in RF tank circuits due to RF 
heating.  Chances are any repair you make will become a conductive path and 
eventually cause catastrophic failure.

I would talk to Multi-tech to see what it costs for a new heavier duty 
bandswitch.  They are all custom made to order.  It wouldn't hurt to ask 
what it costs.  A model 80 might fit, but check the dimensions and clearance 
first.

See http://www.multi-tech-industries.com/rotary_switches.htm
