I've finished my Munin amplifier, driving it with Hermes, and using Alex,
here are my results.
Band	output	PA Gain
6m	52w	38.8
10m	90w	38.8
12m	70w	38.8
15m	85w	38.8
17m	90w	38.8
20m	100w	49.6
30m	100w	50.3
40m	100w	51.0
60m	100w	54.1
80m	100w	55.0
160m	100w	51.7

I put the four 220pf 500V caps in the C25, C26 and C27 positions.  Are there
any other modifications or can anyone advise what I need to do to get 100W
on the higher bands?
I did notice the braid on the back of L4 doesn't cover the wires 100%..... I
can see the wires through openings.  Could this be the problem?
Any advice will be appreciated.

Thanks,
Rick
