[Kenwood] TS850 and SB200

[Garey Barrell]

Simple question.....

IF the relay is NOT capable of handling the voltage and/or current 
requirements of the SB-200 relay ...

Would you rather

1. Replace an external, standard, readily available, easily accessed relay?

or, worst case, (thanks Murphy....)

A. Replace an internal relay available ONLY from Kenwood, buried three 
layers deep and soldered onto a multilayer PC board?
