Re: On a more technical note.....

Good input.  I should have mentioned I have the K-3/100 on order.

I must admit I placed a dab of thermal grease on each of the LPA final
transistors.  I couldn't help myself.  Probably doesn't need it.  But I
certainly feel better knowing that the thermal transfer will be just a
tad more efficient.

the new 10 watt lpa....

Not that I plan on taking the bottom off frequently,
It's ALOT BETTER AND EASIER THAN THE K2,,,,
......and as I did it could only think of the k2's lpa procedure,,,,,
