As far as I know, the 326298 is older than the KU-14194HB.

Speaking of which... If anyone here has a KU-14194HB, check the state of 
  C107 and C108. If they are small and black, change them, they WILL 
leak and C107 will destroy the trace that supplies power to pin 15 pin 
of the 74LS629. Without power there, the VCO will not run => no clock 
signals.
