Did you drill out the rivets holding the coin slots on the upper housing or did you just mask the assembly off when you painted it? It looks like it'll be a real pain to drive rivet back into it in such confined space.As you can see from this picture of the vault, I will certainly be refinishing mine.
Quote from: mentalstampede on March 05, 2014, 12:32:44 PMI've got another quick question for those of you who have QSD3As in an as removed condition: The electromagnet in the coin mech has to do with holding a single nickel in the mechanism until a second one is deposited for a 10 cent rate local call, correct? What condition causes the electromagnet to release the held coin?Also, I am missing the contact on the back plate that the BKX terminal touches when the upper housing is closed. Since I ama ssembling the phone without a post-pay relay and coin switch, is this a piece I can do without?

I appear to be missing this component; at least I sure don't see one. Do you have any idea what the value of this capacitor might be, or can I do without it?I am aware the the brown wires have been cut; I'm going to resolder them and route them appropriately; one to the A terminal, and the other to the BK terminal.
