[Boatanchors] Trying to ID an old Motorola power supply

[Glen Zook]

The TU589TS4 is the Motorola model number of the power supply.  It most probably was used with one of the 250 watt output lowband or highband base stations, like the B93GKB-1100 series.  I probably have a Motorola manual that includes the schematic for the power supply.  I'll look for the manual and scan the schematic if I find it.

Now you have to realize that I have over 1000 manuals on the older FM equipment and it may take several days before I find the correct manual.

The only ID on it is TU589TS4 which is ink stamped on the outer and inner chassis. The only tubes are a pair of 3B28's and there are many selenium rectifiers.
