The Heat-sink design is GE MASTR series .. this unit has been pulled and modified.
Identical castings to a 110 watt VHF GE MASTR II mobile unit that I have in garage
This may have come from a mobile unit or a rack-mount repeater radio.
The 9-pin test-set connector (black plug-in connector in photo) is same one used for the GE MASTR II,
Motorola did not use this style of connector and the GE MASTR-PRO series used a different style of test-set connector !!
The MASTR PRO was also a Hybrid PA design using vacuum tubes for drivers and final PA tube.
GO TO Repeater Builders TIP, and use that GE part number: PL19xxxx
They should be able to quickly Cross Reference to GE Manuals, specifications, etc.
