I don't know if this should be in the jukebox forum, that mainly seems to deal with he audio/software aspects. anyway, I'm planning a MAME cabinet, thought some bubble tubes would look good on the front/sides, like the old Wurlitzer jukeboxes...anybody know how to make these things from scratch? I was thinking about just using some clear aquarium tubing, don't know how to get the bubble effect, some kind of pump I imagine? Or, is there somewhere I can purchase some replacement bubble tubes from a jukebox restorer? I've looked at all the big arcade vendors (Happs, Betson, etc), no bubble tubes to be found. Thanks for any help.
