Sencore PS43 Porta-Pak - Any Info?
« on: February 06, 2018, 10:34:16 pm »
Hello all,

Asking for help in getting a schematic and a component parts list for a Sencore PS43 Porta-Pak (battery eliminator).  I'll appreciate any information you can send, even a photo of the interior and the transistor's part number would be helpful. 

I picked up a burned out Sencore PS43 the other day that doesn't work on batteries or on wall power.  I took it apart and found an overheated point-to-point pc board and sticky remnants of something that didn't come from a resistor, diode, or transistor.  All of the discreet components, one NPN and a bunch of diodes and resistors, were in good shape, so I'm guessing someone before me did their best with a 900W soldering gun.  (Maybe replacing burnt components with whatever they had on hand?)  The transformer appears to be in good condition.  I get different voltage readings from the secondary side that goes to the PC board, for what that's worth...

Anyway, I've spent a long time searching and have decided I'm looking in the wrong places so need your help please.  It's odd that all I'm finding are a few photos showing the front panel.  It would be very surprising if the PS43 turned out to be a rare piece of equipment.

Please let me know if I should have posted this request elsewhere so I can delete this and put it where it belongs.

The transistor on the pc board is a common 2N3904.

Hi,

That's great news, thank you.  Really doubt there's a problem with them, but while you're here, do you have a the part number for the diodes?
       Sitting here rhetorically wondering why the PS43 schematic is so difficult to find...


Thanks again,
Don (aka Bud)
