[Kenwood] New to Kenwood

As a follow-up:

Just go to the classifieds forum on qth.com and search for him or 520s and
you are bound to run across him there.  Ken Kemski (k4eaa.com) has
replacement HV kits and the resistor kits for the PA unit.  I had to redo my
830s after the 20 ohm resistors were pushing 40 ohms each.

Both are great sources for the hybrids

Bob Mansker is where I get my parts...he usually has everything you need for
hybrids

East Coast Transistor shows it as discontinued.  I think I may have 
found one somewhere else though.  I need a very clear schematic of the 
final unit.  The one I downloaded was fuzzy and I could not make all the 
components out.  Do you know where I can get a schematic for the 520s?
