Larry,
I suggest your first step is to count the turns on all the toroids in
the Low Pass filter area.
Count the number of times the wire passes through the center of the core.
One extra turn would lower the cutoff frequency of the low pass filter.
Since many bands are arranged in pairs - 40
I got several favorable replies to my proposal below, so let's start
right away. 40m has been S8 noise level for me, but usable. 20 is very
good! I'll going to pay most attention to 20, but I'll listen to 40. I
think we'll have a more viable net this way. Even if it only results
in a few
Robert,
There are lots of choices. Google on antistatic mat to find several.
I can't say that one is better than the other, just pick one and use it
- it will be better than nothing at all.

Hello Windy:
The lasts step (right column) of page 54 of the KPA100 Manual says:
IMPORTANT: The hardware holding the RF power transistors
in place will loosen slightly during initial use. After 5-10 hours of
normal operation at 50 watts or more, remove the KPA100 assembly
and its shield, then
Robert,
There was lots of discussion of this on the list a month or two ago,
but suffice to say there are many sources and it seems a lot of them
cost about $25. Nobody had any significant reasons to recommend one
kind over another.
Here's a cheaper source, and while you're at it, a fine
