Because of the bulb size you are referencing I’m guessing this is a Seeburg ? If it has original ballasts they are oil filled and hazardous. Ballast are cheap. I replace all in my restorations

When the lamp and ballast are good, you can short across the two starter terminals and release and the bulb will light. In fact I have a very old fluorescent light here on my desk that doesn't use a starter. Instead it has a normally open momentary red switch/button to turn it on (or make it "start") and a normally closed momentary black button to turn it off.

The interference suppressor would be common to both ballasts so that would be the place to start. Usually the suppressor doesn't feature on US machines but does on export machines (it is an EU regulation). They do fail fairly frequently usually shorting and taking out the fuse. I used to replace them with suppression units for domestic appliances (cheap to buy) but latterly I stopped doing that and just remove them completely when they fail.

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/ http://jukebox.markmail.org/ _______________________________________________ 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/
