Hello All,

  I trying to find the proper replacement for the Timer Chip in the light sequencer.  
Seeburg # is 64-309778.

   Any help much appreciated!

Hi Scott,
Any 555 will work - Hint: If the diode is banded with a brown band- CHANGE it (1n4002 or better)! Ron Rich

Hi Ron,

  Thanks for the tip.  Are you speaking of the zener diode or all of them?

Scott,
Did I say "zener" ? A 1N4002 is not a Zener---Ron Rich
