My mother purchased this mic at a flea market for about 50 cents. And it's been displayed on a shelf ever since. All I know about it is that it's a mic made by Presto Recording Corp somewhere between 1930 - 1950. Upon researching online I couldn't find anything about it. So my question to anyone who might know, How valuable (if at all ) is it? and is it a ribbon mic? Thanks!
I'm trying to get this mic back into working shape, or atleast get some repairing experience from it. So far during my internship I've only repaired cables. Could I remove the cable from the screw and solder a balanced mic cable to it? I'm pretty sure it requires some kind of power supply, any suggestions? Thanks for your reply
