[Hammarlund] Landed on my doorstep]

> You'll love your SP-600 when you're finished, Gary.  It's the one

> The rebuilding isn't bad at all, as long as you're not in a hurry (and 
> it doesn't sound like you are) and are patient enough to work on one 
> small section at a time. True, the RF deck is just a little 
> inconvenient to remove and replace, but the beauty of it is that -- 
> once out of the radio -- you can work on it as a separate, easy to 
> handle module.  It's a whole lot easier than twisting and turning to 
> get into tight nooks and crannies in a big chassis.  The SP-600's a 
> ruggedly built set put together by trustworthy assemblers, and that 
> always makes reworking easier.  As a bonus, one of your manuals will 
> contain pictorial diagrams of the interconnections between receiver 
> subassemblies.  But, of course, take plenty of pictures or make 
> sketches of the wiring before you unsolder anything.  I find a digital 
> camera to be one of my most valuable restoration tools.

> If you've worked on a Hallicrafters SX-28 or SX-42 or 62, -- or a 
> Collins S-Line component --  you'll find the SP-600 an enjoyable 
> "piece 'o cake" (relatively speaking).

> Incidentally, I have two SP-600 JX1 receivers.  One was previously 
> recapped strictly with economical disc ceramics -- a la later 
> Hammarlund.  I recapped the other one with a theoretically superior 
> combination of more expensive Orange Drops and yellow tubular film 
> caps as appropriate to their circuits.  There is absolutely NO 
> difference in the performance or sound of these two radios. And, in 
> fact, the one with the litte red disc ceramics looks a lot prettier 
> underneath.
>
> Have fun -- and try not to wait until next winter to get started.  
> Some of us are anxious to hear of your adventure along the way.  I 
> predict Al Parker and Andy Moorer will become your very best friends 
> in the next year.
