Does anyone know where I can buy a replacement pin for a transformer/pre-amp like the ones in the picture? In an attempt to straighten one out, it snapped off. Are they difficult to solder?

If you look at the ones in the top row, you'll see the pins. They are about a half inch long.

Thanks.

Those pins are generally hammer tacked through board and then soldered... I'm not sure where you could buy a replacement since they're generally used in a factory/production environment... I don't think you'd a problem using a piece of heavy buss wire as a replacement though. Desolder and pull the brocken pin out... then solder the heavy gauge wire through-board.
 
I was in a bind once and used a paperclip. Removed the broken pin and made a new one from a paperclip.
 
if you decide to try a paper clip 2 suggestions...

1. the paperclip doesn't like solder so use flux and tin it first...(apply some solder clean it off to make sure it's stuck on good)

2. make sure you dont apply to much heat to the unit... use a roach clip if need to help drain the heat away...

Doesn't really apply in this application... if you clip a heat sink onto the pin... you're just going to have to heat the board longer waiting for the pin to heat up... Kind of the opposite of what you really want...
 
Thanks for all the suggestions...I just left a message with ADK to see what they would recommend. If they don't respond, I'll definitely try one of those ways.

Thanks again.

Any wire wrap IC socket pin can be cut and soldered to the transformer board in a few ways. Be creative. The pin only has to make a good connection.

Thanks, so will these do the trick?

First, is the pin you broke round or square?

Is the part on a ciruit board or potted?

If the part is a circuit boarded device and the pin is square, any wirewrap socked pin should work as the square pins are a standard size.

If the pin that broke was round and the device was potted, then you have to very carefully use a dremel tool to cut some potting around the pin so you can solder a round pin to the stub. A round pin can be taken from a resistor if need be. After soldering to the stub, you can pot the stub with epoxy.

It is an easy repair for any tech but you have to be careful.

Not seeing the part in question, I cannot really tell you exactly how to proceed in your case.

Good luck.

Thanks for the info.
I'll try to take pictures of the actual part tonight, but I think it's round.

I suppose I can go to an electronics store (not Radio Shack) to get it repaired.

Thanks again.

of course it applies... you've never really done this have you??? was a pro tech for @15 yrs here... and it's avery common thing... the purpose is to not allow the heat into the unit any more than necessary... or are you heat sinking the wrong end??? :cool:

The only pins I saw on the attached picture looked to be through board and only connected to the circuit board. I think there's some confusion on this thread about what pin is being discussed here. I think it's the pin connected directly to the board and then traced to the transformer or amp component on the board. I don't think we're discussing one of the pins directly out of the transformer or Op Amp (I wouldn't call that a pin).

And yes I have... only five years though

Heat sinks for soldering are for wimps :p
