As I mentioned elsewhere, I have ordered a replacement roller/brad set for this unit. Questions:
1. Does anyone have a unused loose roller and would be willing to measure it for me? I'd just like to get a feel for how large a new one is, and compare that measurement with the original that's on mine. For all I know, the current roller may in fact be almost "full" size, in which case I will hold off on replacing it until a later date.
2. How do you go about removing the mounting brad? It seems that the brad/roller assembly is attached to a rather thin brass piece, so I suspect one must be very careful so's not to distort that brass "arm".
I have to say there's something about this old transformer I find very charming...and I thank you in advance.
