Re: QMX - What's up?

I have considered removing them as a last try. I've used them in my QDXs, but there was room to build a much beefier heat sink there. Also, as I've said before, with the number of dying BS170s I've had the sockets save the board. We'll just have to take it one thing at a time.

Thanks for the hint on using low temp solder. Good idea.

Thanks, Cliff, your pictures are perfect.
I still suspect poor heat removal from the BS170s.? Can't prove it from here in Michigan though.
If you decide to eliminate the sockets in the future, I suggest using low-temperature desoldering alloy to remove them.? Less chance of damaging your board.

Before you install new BS170s, clean all of the weird alloy off with desoldering braid and flux.
