[TenTec] Low power output on Argonaut V

Need some advice from the guru's out there.  Of course, it's Saturday, and 
TenTec service is
closed on weekends.

I've got an Argonaut V.  Been using it fine for a while, keeping my power level 
around 5W, but I
decided to actually up the power to the max to see what it would do.  I was 
quite surprised to see
that I could not get more than 14W out of it above 30m!  This is both with the 
built-in power
meter, as well as an MFJ-949E.  

Something isn't right here.  So I checked the SWR was from the rig to the tuner 
(since I had a 1:1
from the tuner on out to the antenna).  I switched into bypassed dummy load, 
and keyed up on CW,
with the power set to max (full clockwise).  It still showed 14W and the tuner 
said 1:1 SWR, which
is what I expected.  But when I use the built in SWR meter (key up, hit the 
"split" button), it
showed an SWR greater than 2.5:1 (pegged the meter).  Trying the reflected 
power function ("A-B"
button), it shows a reflected power of around 7W.  

160m - 18W
80m  - 20W
40m  - 21W
30m  - 20W
20m  - 13W 
17m  - 7W
15m  - 12W
12m  - 7W
10m  - 14W

What's going on here?!?  Help!

73,

P.S.  I've done a master reset and I'm using firmware 1.70.
