PC-100 US Version

[Maximilian Hohmann]

Hello again,

you made me curious enough to open one of my PC-100 Printers (this one is a PC-100C) to look inside and take some measurements.

This is what the transformer looks like from the bottom side:

Is is 67 x 55 x 48 (height) millimeters big. The power rating is 20W. There is only one primary winding for 220V and two separate secondary windings. Between the red and yellow cables I measure 24V and between green and blue there are 9.5V

Beside the transformer there is quite a lot of empty space in the housing. I am pretty sure that a small 110V to 220V tranformer (mayby taken out of one of those cheap adapters) would easily fit there. If I were you I would try that solution instead of finding a matching 220V transformer. Unless you can find a broken PC-100 that you can cannibalise for parts.

Hope that helps,
Max
