Sex 3.0 C4S upgrade
« on: October 09, 2021, 11:02:27 AM »
Just installed the C4S upgrade kit. I get 67 volts on OA and 48 volts on OB. Also one of the led's on the B side is not lit. Problem?
Thanks
Joe

Can you post a picture of your installation?

You have a backwards transistor.

Okay, I see it now. How does one go about desoldering that? The Board came to me already built.

There are a few ways to deal with this.  You can purchase a replacement PN2907 transistor, then cut the one off that's on there now but cut it so that as much of each lead is left sticking up out of the board as possible, then heat up each pad and slip the lead out, then install the new transistor.

You could also attempt to use solder wick, a spring loaded desolder pump, or an electric vacuum desoldering tool to remove the solder that's there, then turn the transistor around and solder it back in.  The PN2907 should still work just fine.

If someone else built this, I would send it back.

Well I got this last winter when I purchased the sex kit. The upgrade came with the board already assembled. Is this the way they come now? I kinda thought it was weird that the the instructions show how to assemble the board when mine came prebuilt. I guess I will attempt to desolder the transistor and turn it around.
Thanks

Our boards do not come pre-built.

Are you sure you got this from us?

Yup, ordered it at the same time I bought the sex kit. Another odd thing, it had one completed board and one blank board all the wires and hardware but no components to populate the the blank board.

This is really odd, as the building where the packing and order fulfillment happens often doesn't have the tools present to populate and solder up a board.  When these kits are packed, parts are laid out and several kits are packed all at the same time, so this would be highly unusual.  Moreover, if you asked for a built board, that request likely would have gone to me.

Check the security cam for ghosts soldering in the wee hours .... maybe C4S stands for "Check 4 Spirits"???  :o :P
