Request PS-3 Help

[rfb100]

Greetings group  --  I'm trying to put a newly-acquired PS-3 regulated 
power supply in proper condition.  The problem is that one portion of 
the circuit overheats badly, and apparently  has done so for a long 
time.  It looks like the unit was built in 1957 or so, used a little 
bit, and then put awey until now.  Anyhow, although it is a 
simple,circuit, it isn't an AA5, so I need help.  If there is anyone in 
the group who has a properly functioning PS-3, I would appreciate a 
contact and then I can go into detail using the schematic describing 
what troubleshooting I have done.  There are no voltages shown anywhere 
for the circuit; that doesn't help.  Appreciate any and all advice.
