The TR7 can handle the SB220/221 switching with no external relay/soft-key needed.
I have been using this combination for years with no problem.
Many of the newer rigs have rather flimsy relays and require a modification to the amplifier or installation of a "soft-key" to handle the current required to switch the SB220/221...NOT the TR7.

Is anyone using this combination?
I wonder if it's advisable to use an external relay to control
the amp, or whether the TR7 switching can handle it as-is?
Sage advice of the Drakelist greatly appreciated!!!
