The reason that many of the "other" radios have built in tuners is so
that the bipolar amplifiers could be made ot work into a reasonable 3 to
1 SWR range without folding back power.
Many of these early radios without tuners folded back or distorted with
SWR of 1.5 or 2 to 1. Many of the built in tuners are mere band
flatteners capable of providing the radio only a 3 to 1 or so capability
which is no better than the robust TenTec amplifier design does without
a tuner.
The TenTec design approach of designing a Crunch proof 100 watt
amplifier with at least a 3 to 1 full power capability will make it easy
to use many antennas over the whole band without tuner and without
blowing up the radio.
