Ed, I be never seen capacitors in that circuit but perhaps they help smooth out the voltage?? Regardless, if I replaced lamps and starters I’d probably replace the ballasts at this point and remove the caps. There’s nothing else in that circuit, Mauro

Have a customer whose fluorescent lamps went out. Jukebox takes rather rare F25T12/CW/33 lamps but I found a pair and replaced both FS-25 starters. One of the new lamps blinked for a second then went out. The other won't come on at all. Typical of failed ballasts? I noticed the ballasts are also connected to "noise suppression capacitors." Is this typical? Maybe bad capacitors? Are they really necessary? Should I try bypassing the capacitors or try replacing the ballasts? Both? Seems odd that both would fail at the same time. I'm sure this isn't rocket science but I was expecting the new lamps to start right up so it was kind of disappointing & the customer is frustrated. Any suggestions appreciated. thanks, Ed _______________________________________________ Jukebox-list mailing list -- jukebox-list@lists.netlojix.com To unsubscribe send an email to jukebox-list-leave@lists.netlojix.com %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s Searchable Archives: http://jukebox.markmail.org/
