Yes it is James. (I already suggested he check out your webpage or drop
you a line).
BTW, you didn't mention the infamous red-white wire swap on E13 ;)

The NAVSHIPS manual is a copy of Issue-6 of the standard Hammarlund
SP-600 
manuals. Curiously enough, it doesn't really quite cover the JX-6. For 
instance, the JX-6 has the 6-wire RF deck, but Figure 15 (page 37) of 
Issue-6 (the NAVSHIPS 91661 manual) shows the 7-wire RF deck. You get a 
little surprise when you go to overhaul the RF deck.

There is no Hammarlund manual that accurately describes the early models
of 
the JX-6. The closest you can get is the Army manual TM 11-851. Figure
100 
shows the early-issue R-274B. The later issue R-274B is shown in Figure
102. 
If yours is a later model, then the second set of schematics in Issue-4 
accurately describe the unit as well. You can tell the difference
between 
the early and the late models by looking at terminal strip E13 (right by
the 
chokes and main power filter capacitor). If it is a rectangular block
with 
posts, it is a later model. If it is a linear terminal strip, then it is
an 
earlier model.

Ain't this fun?

Is there a specialized manual for this radio: SP-600 JX-6, R274B/FRR
like 
the Navships manual 91661 that is shown on the Hammarlund Historian site
or 
will any SP-600 manual do? If I need this Navships manual 91661, does
anyone 
have one for sale? thanks,
