[Yaesu] Field vs. Mark V

The MARK V FT-1000MP (non-Field) has cleaner transmit with it's Class-A
operation P/A. I don't think the Field has Class -A.

>From Yaesu:
The Mark-V is the first commercially-produced Amateur transceiver to provide
Class-A operation for its power amplifier. When engaged by the front panel's
[CLASS-A] switch, the PA bias is changed dramatically, and the Mark-V puts out a
75-Watt signal envelope of astounding purity: during Class-A operation, SSB 5th-
and higher-order Intermodulation Distortion (the kind that contributes to
"splatter" reports) will drop to the -80 dB range! And while the Mark-V's
Class-A feature does not directly affect your linear amplifier's performance,
the extremely clean drive to your linear will result in dramatically cleaner
overall signal reproduction.

Is the only real difference between the FT 1000 Field and the Mark V the extra
100 watts? Don't have a lot of experience with Yaesu HF rigs.
