[AMRadio] : BC 610 needing POWER 220VAC

I had an idea that it draws too much current for a common 110 circuit.  My 
centurion amp requires 220vac also.  Otherwise it would need 30 amps at 110 
and that is too much for most wiring in homes.  We never tired to operate 
that transmitter and I don't know if he still has it but I bet he does.  He 
has a lot of STUFF that he never uses.
