[GreenKeys] ASR 33 papertape reader power supply

[Jones, Douglas W]

I note one of these up for auction on ebay
-- http://www.ebay.com/itm/271588275575

The supply is missing in the ASR-33 we're restoring here at
the U of Iowa.  Trouble is, there seem to have been several
models of the paper-tape reader supply.  All I know about
the supply I am missing is that the dangling plug that goes
to it ends in open air hanging in the back of the base, and
my TTY is definitely older than the one the E-bay seller
has broken up to sell off.  (He has a number of the other
parts -- main CCU, main unit with keyboard and reader, etc).
The seller's other stuff is PDP-11 parts, so I'll guess that
the TTY is contemporaneous.

So, should I bid on this or can I get the replacement some
other way?  (I'd be happy to bid on it and then trade for the
right supply, if that's the best way for me to get one for
the TTY we're restoring here.)
