Booster Voltage Mismatch

The older PB105 / PB110 have an internal adjustment like the PH Pro. They can be adjusted to match. These use a 15 V AC power supply. BUT the newer boosters PB5/SB5/DB5 use a fixed voltage 13.8/12v DC power supply. If you wind up with a mixture of both your best solution is the drop the older units down to 13.8v to get matching power.
