Ken, I am not sure you are reading the rules correctly. A manufactured amp
that is not type accepted may not be commercially sold. However, it is not
illegal to use the amp - even if it takes only 4 watts of power and outputs
500 watts. I can build that amp myself and use it and it is perfectly legal
If I import that amp for my own use I believe I can use it. They just
cannot be commercially sold. This of course all amps have proper spectral
purity.
JMHI of the rules.

Here is a direct quote from FCC part 97. I think item 5 may answer your
question.
(b) Any external RF power amplifier or external RF power amplifier kit
(see §2.815 of the FCC Rules), manufactured, imported or modified for
use in a station or attached at any station must be certificated for use
in the
amateur service in accordance with Subpart J of Part 2 of the FCC Rules.
This requirement does not apply if one or more of the following conditions
are met:
(1) The amplifier is not capable of operation on frequencies below
144 MHz. For the purpose of this part, an amplifier will be deemed
to be incapable of operation below 144 MHz if it is not capable of
being easily modified to increase its amplification characteristics
below 120 MHz and either:
(i) The mean output power of the amplifier decreases, as
frequency decreases from 144 MHz, to a point where 0 dB
or less gain is exhibited at 120 MHz; or
(ii) The amplifier is not capable of amplifying signals below
120 MHz even for brief periods without sustaining permanent
damage to its amplification circuitry.
(2) The amplifier was manufactured before April 28, 1978, and has
been issued a marketing waiver by the FCC, or the amplifier was
purchased before April 28, 1978, by an amateur operator for use at
that amateur operator's station.
(3) The amplifier was:
(i) Constructed by the licensee, not from an external RF
power amplifier kit, for use at the licensee's station; or
(ii) Modified by the licensee for use at the licensee's station.
(4) The amplifier is sold by an amateur operator to another amateur
operator or to a dealer.
(5) The amplifier is purchased in used condition by an equipment
dealer from an amateur operator and the amplifier is further sold to
another amateur operator for use at that operator's station.
So technically you can't use an non-type accepted amplifier built after
April 28, 1978
if it is bought from a non-ham or from a vendor that bought it from a non-ham.
interesting.
