[Central-Electronics] 600L variants

[Brian Harris]

Bob,

I have four 600Ls, one of which is serial number 1 (actually 560001 if I remember correctly).  Since it's the first I think it's safe to assume the only square cornered version would have been a prototype or an artist's rendition.  This particular amplifier also has the very rare, ganged-to-the-bandswitch, coax switch option.  I think it's safe to assume that, being the first, it probably initially belonged to a CE employee.  I bought it for $150 in Springfield Mo at a tobacco shop that also sold consigned ham gear.  Such a deal.

Subject: [Central-Electronics] 600L variants

Now that I've got my 10A and 600L combo perking along nicely, I've 
become curious about something.   It looks like the 600L was first 
introduced by means of  full page ads in early issues of QST for 1955  
But the picture in the June ad shows a cabinet with square corners just 
like the CE exciters, only larger.  Yet every 600L I've seen has the 
round-corner cabinet like the 100V,  which wouldn't come out for another 
3 years.  So I assume that the 600L was made with both cabinet styles, 
but wonder if anyone can confirm this?

More interestingly, a very different-looking 600L was actually announced 
several months earlier, with the first ad appearing in the March 1955 
issue.   While the technical description is identical, the front panel 
layout was different and the cabinet size was three inches narrower at 
14 5/8" wide.     My guess is that this narrower version was never 
actually produced, except perhaps for a few prototypes.
