Today (Sunday, 6.mar.2011), the electrician of Carmel hospital, came to the copying room of the storage of Carmel hospital, to maintenance the 2 lamps fixture near the door, which contained the >30 years old ballasts. And because i haven't my camera, i couldn't photographed the ballasts, so i asked him to get me one of these antique ballasts and that i collect it.
There were two ballasts made by Eltam in Israel, that shared with one metal (Silver colored) PFC capacitor, all are replaceable and screwed to a tray.
The relatively new Osram 36W T8 lamp, was actually installed on one of these antique ballasts, so this way it did problem (Initially ignition period of 7 secs, followed by ignition problems, until the lamp totally stopped working).
These ballasts are actually aren't rapidstart ballasts but called "Perfekt Start" ballasts (Eltam original "rapidstarts" for 20 and 40W T12 lamps probably operated similar to the UK quickstarts and trigger starts), and uses on thermal starter.
I will post pictures of the ballast i recived when my camera will be returned.
