Quoted from The--Who:My 0-9 brass contacts are filthy and I have yet to clean them. I had the same problem last week with my Cross Town and when I followed the advice of the guys on here the number match lights came back to life. I’ll let you know how I make out. Thanks!!!!
Didn't realize "Mibs" still has bells and that big 0-9 unit. I just checked on IPDB. I thought it had chimes and a later type unit.
Edit: Apparently "Mibs" is the last Gottlieb with bells. Chimes were used thereafter.
