Tony, I  am a little confused.  To buy a transceiver as good as a Mark 5
and then to put all those limitations on the amp, particularly the 220 line?

But if that's really where you are, I would suggest you look for a really
clean Drake L4B, L7, SB-220/221 or TL-922A.  The 3-500Zs are almost
bulletproof and will coast at 600-100w output.  The only precaution with
these older amps is that you may need to use a soft-switch interface of
some sort, because the voltage (at least on the SB-220/221) is too high to
be within ratings, even for the Mark 5's TX GND relay.
I looked over the "cross-needle meter" Ameritron amps at Dayton last year
(I think the AL-811 is one of them) and was not impressed with the
construction -- they just looked light throughout, compared with the older
generation of Ameritrons such as the AL-1200 and 1500.
