[ASR33 Reader power supply]
Hi
It is a small board that is usually on the right
hand side of the printer=2C behind the line/local switch.
On machines with a floor stand, it's often clipped inside the stand at
the very top.
It has a power resistor=2C cap=2C molex connector ( I
think
9 pin ).
I am pretty sure it's a 15 pin connector (almost all connectors in the
Model 33 are 15 pin Molex 0.093" ones). There were some 3rd party
versions of the Model 33 with Teletype mechanics and other electronics
(the Data Synamics 390 is probably the most common one), and on those the
reader PSU is totally differnt (it may even be isolated from the power
line...). If you haer one of those machines all bets are off :-)
If you can't get the original Teletype one, I would have thought it would
be fairly easy to make one. I don't recall there being anything hard to
find on that PCB, and layout is not critical. You could make it on
tagstrip, for example.
