[Amps] ARB-704

[R.Measures]

**  Bob --  Although it's more work on your part, one solution is to 
convert the SB-201 from a negative to a positive relay supply V, remove 
the original relay and cockamamie bias switching scheme, and do the 
high-speed switching mod so it can keep up with modern radios -- i.e., 
not hotswitch.  With Kenwood radios, use "RL" (+12v on Tx)  on the 
accessory jack to actuate the high-speed relays in the amplifier.  ref:
