[GE] Transformer

The BT-20-A broadcast transmitter uses several filament transformers for 
the various stages.  All of them are rated at 100 volts AC primary.  All 
of the primaries pass through a voltage adjusting rheostat and volt 
meter to insure proper filament voltage on all tubes.   I'm sure GE did 
this to insure there was plenty of room, high or low, for various line 
voltages encountered.  However, it's created a problem since I haven't 
seen a lot of 100 vac primary transformers floating around.   Any help 
locating  a 100 vac primary/5 vac @2.5 amp secondary would be greatly 
appreciated.

Thanks,
Rick/K5IZ
