I have an ASR-33 and I have a manual reader power pack question (183087).

There were two version of this board.  The original version was designed
to mount in the pedestal and had the 120VAC power going to Spade Lug
connectors on the power back power (T1 & T2).  This board had only 6
contact in the J1 connector.  This could be mounted in the pedestal or
the UCC-6.

The newer power pack board removed the spade lug wires and added 2 more
connections to the J1 molex connector on the power pack board. These two
new connections provide the 120 VAC on pins 1 and 13.

The schematics that I have 1965 so not show these extra two connections.

Does anyone know where I can find a new schematic so I can see which pic
is hot and which pin is neutral.

Also, where is the best place on the CCU-6 to get 120VAC to route to the
reader power pack?

Thank you,

             Mike
