[Elecraft] Is it possible to connect a amp to the K2

[James Brown]

Eric:

My SB-220 uses +123VDC through a 5Kohm relay coil keyed to ground. There is 
no diode protection from back-emf across the relay coil, but there is a 
.02mfd cap on the low side of the relay coil to ground.

Regards,
Jim Brown, K5JAZ
