As I stated earlier
Ameritron is shipping the last of their ALS600s now ... the NEW ALS600
will have a new faceplate with the capability of hooking up an ARI500
interface via telephone lines (RC45) between the 600's faceplate and the
ARI500. THIS hookup gives you AUTOMATIC bandswitching as you change
frequencies on your exciter.
The ALS600"S" is simply the ALS600 WITH A SWITCHING POWER SUPPLY !!! It
has been sold in that fashion for about 4 yrs or more ??
Ameritron is bringing out a kit to backward convert the old ALS 600s to
the new version which is shipping as old supply stocks are used up.
iow, if R&L needs a dozen ALS600s with standard PS, Ameritron may ship 3
of the new version and 9 of the old version. Which one you get depends
on how good an "in" you have with R&L. I believe that a couple of these
dealers have a waiting list.
Just REMEMBER, do NOT order an ALS600S and think that you are getting
the new ALS600. You may or may not. But you WILL get a switching power
supply with whatever amp you do receive.
hope that is cleared up now ... <G>
cheers
