Well Paul I don't totally agree with you...Dale W5LJ runs his KWS-1 on
AM a lot and it sounds great...As far as the amps on AM Robert W5APN
uses his 30S1 with a Ranger at about 350 watts and sounds great as does
he when he uses his 30L1 on AM...Only about 125 watts there..  I run my
Warrior at about 350 but is has 572B's in it and Fred W5HTR is running
an AL811A at about 250 watts...So some of the mini amps are working

Just a pennies worth  LOL...

Joe before you posted your update I was prepared to
modify my presumptions about the junior Collins

So I am back to my opinion none of these smaller,
less-vintage units is capable of adequate AM. The
deterioration in that capability started with the
transitional 75A4 and was complete by the KWM-2 and
32S.  Even the KWS-1 is inadequate on AM.

This disparity and lack of AM functionality is
probably why there has been such a segregation between
the two groups of Collins enthusiasts. Many if not
most of those who favor the junior models don't
support the senior models that fully produce wholesome

The few who collect and enjoy both sets seem aware of discussing them in
mixed company.
