Music Man Amps

Hi. I have what i presume to be an hd150 with a blown ouput transformer. I am presuming the failure of the selector switch going resistive led to its demise.
Chassis number BO-2224-DOM which I cannot find anywhere. Produced 6-83, chassis serial C009420. I measure about 2K to 8R impedance which makes sense, but I cannot discern the DC resistance of the primary. Anyone that could take a quick check of their amplifier and do a resistance check from pin 3 to pin 3 on the output tubes would go a long way to helping me resurrect this beast. Looks like I need an aftermarket one as there are none to be had from the resellers. Thank you.
