Do you think it is possible to drive a 16 pill mobile amp with an A/C tube box? I was thinking of using a bank of batteries for the 16 pill at 18 volts and hook up my 200 amp battery charger. The A/C box is a Firebird 500. I can probably just use 12 volts instead of 18 volts. I just want to cruise with the 16 pill. I am usuing a Maco 5 element for a antenna and probably will have to change the Gamma Match. Any thoughts.
