light effecting GR43's?????

[bob harper]

hi all, GR43's effected by light???  this jukebox pcb is now finally working, had to alter some resister values away from spec, in order for it to work....but all is now working as it should...in the daylight! i wondered why some times its now behaving as it should, but other times its not....it then dawned on me its only at night it plays up with the workshop lights on. i have now proved this...if i cover the pcb with a towel in daylight  the timer tube ignites when it should not, if i take the towel off, all is well....is there a solution to this?  bob

What I was thinking was that if the lights (if any) inside the jukebox are on while in operation that may cure the issue.   Ira.
