Hi Bruce ..
       Go to  http://www.mods.dk/index.htm

Then to Kenwood..... 950... and look for the bulletin  "Countermeasure
against cold solder joint at the resistor block; CP1-CP4 in the PLL unit."

        I had the same problem, and this cured it..  BTW  I found that the
best way to resolder the joints to CP1-CP4, was to scrape the paint off the
trace a fraction out from the pins, solder to the trace, and let the solder
run back to the pins. I created shorts between pins, when I tried to solder
directly to them.. I also soldered some of the plated through holes in the
vicinity of CP1-CP4, and it was cured..  Use a good iron...NOT TOO HOT!
      Good luck OM
