[Hammarlund] SP600 ReCap BBODs

[anchor at ec.rr.com]

Hi Wes,
  I'm away from home this wkend, email is a bit difficult.  Just for reference, go to 
www.hammarlund.info   On the intro page, download the 2 parts of "The SP-600 Compendium", put together by Perry Sandeen.  Also, go into the site to the service section, and look at/download the large section on recapping the SP-600 that was written by Ray Vasek.
  That should help you out.  You'll get lots of replies on how to do it, my recommendation is to work with the schematic at hand, and identify every cap you replace as you do it.  You'll learn about the circuit, and if you mark them off as you do it, that will help.  Most of them are bypass caps.
  Supper time here.
