I am working on my first amp build (a M2 clone) and at this point I'm wiring up the power supply. I began connecting the transformer to the rectifiers today and found that the Faston 250 connectors were pretty loose. They're made by TE Connectivity. For comparison, I tried one of the Faston 205 connectors used on the power switch, and it was quite snug - it took a big effort to get it back off. I tried squashing one of the female Faston 250 connectors with pliers, and I got a snugger fit (no surprise there). I'm wondering if tampering with the connector likely weakened to metal to the point where I'm asking for trouble. I'm also wondering if another brand of female connector will work better?
These connectors must be used as intended, with both parts made by the same manufacturer,
and were intended to fit together. Otherwise, it's pretty much a crap shoot.
Fitting one on something like a generic rectifier block is undefined, and the results are unpredictable.
Soldering is much better in that case.

I would expect connectors from TE to be of good quality. Double-check the specs on that connector. There are two spade thicknesses - 0.51 and 0.81 mm. Make sure you're using the correct connector for the spade.

Thanks Tom. I suspect you've put your finger on it. The spades are probably .51 mm and the female connectors I have are probably designed for .81 mm. More fun searching around on the Mouse web site awaits me.
