I am going to replace my msr2000 amp with a henry amp 350 mw in 100watt out. Problem is that the exciter does not key without the original amp in place. There is a three wire plug that goes behind the msr amp that seems to feed the tripler stage in the exciter. What should I do? Can I feed it constant 9.4volts It seems to switch in during transmit.
