Recently purchased a 10-da (dynamic) head in good condition to use with my Icom 740. I have been using the old familiar D-104 (xtal) head. No more than the usual troubles so far. Now, I have some concerns, that needs to be allayed. Is there anything that I will need to do to the tug-8 stand or the radio? Whoever put the mic plug on the radio broke off the unused pins. The stand is from 8/75, if the date has any bearing on the circuit.
