[Hammarlund] SP-600 J-20 manual

[James A. (Andy) Moorer]

I don't know the exact details of the J-20 model, but you can download any 
or all of the Hammarlund SP-600 manuals that I know about on my SP-600 page, 
http://www.jamminpower.com/main/sp600.jsp. If you can't find documentation 
there for the exact model you have, then it probably doesn't exist.

To pin down the exact wiring of this unit, I need the answers to these 5 
questions:

(1) Is it the 6-wire or 7-wire RF deck? Take the cap off T1 (little box 
bolted onto the right side of the RF deck) and count the number of wires 
going into the RF deck.
(2) Are there two 25-watt wire-wound power resistors bolted to the side of 
the chassis over by the power entry connector?
(3) Is there anything connected to E16-6?
(4) Is there anything connected to E17-1, E17-3? If so, is it a 100K 
resistor or a 10K resistor?
(5) Is E13 a linear strip or a rectangular block?

With the answers to these, I can tell you exactly which of the manuals on my 
web page correspond to your unit.
