I recently bought an old playfield from recel, it's either underwater or the 1 player torpedo versions. It seems like somebody started to dismantle the playfield, all the lamp sockets are gone, the wiring is missing and all the EM parts like the bonus unit are gone too. This means I'm left with the coils and some of the switches, the plastics on the other hand are all there.
Since I really like the look of that machine I'm not going to use them as spare parts but I'm going to restore it back to life using Arduinos, but since I don't know much about recel I need some information before I start my work:
The playfield is still good and covered in the recel, mylar-like coating. It's only slighty coming off in some areas so I'd like to keep it on. What kind of cleaner do I use for this coating? How do I treat this coat after I cleaned it? Do you apply wax or do you just play on it without treatment?
The next big thing are the coils. What kind of voltage did recel use for the coils? I worked on Williams EM coils, they run fine with 24Volt, is this what recel used too?
Last thing, the mechanisms. Recel used a spring wound around the flipper shaft mechanism (I don't know what it's officially called, see the attatched picture . I only know Williams flipper mechanisms which have a spring around the plunger, those are easy to replace. How do I work with the recel ones? How do I get them off, and what kind of spring would be a fitting replacement?
Thank you in advance for your help, I already looked at the few manual scans that are out there but I really can't find the answers I need to start working.
