[Elecraft] Soldering iron tip temperature for KPA100

Sun Aug 4 13:48:01 2002

I, too, found the WTCPT 800 deg tip (PTF8) to be perfectly
adequate for tinning and soldering the power transistors and
the T1/T2 transformers. The secret seems to be to lay the
tip "on its side" rather than use the point, this provides more
surface area.

I used the 800 deg tip to build the whole thing and had no
problems with lifted pads, etc. I found it takes less time to
make good, clean joints.

And while we're on the subject of speakers, I find that the K2
speaker mounted on the KPA100 heat sink sounds MUCH
better than on the original top.
