If it is the Blk desk mic that looks like a Turner desk mic and requires a 9-volt battery, then it is a turner +3 desk mic. Turner mic co. when in business back in the days made them for Lafayette Radio Electronics. the mic is a Turner with the Lafayette name on it, so wire it up like it was a turner mic.
Please advise me to what is a good replacement mic for my SR-497HPC... Answer: 497 is "wired like Cobra", so many choices available. That radio does not need a power mic, so purchase a stock "coffin style" mic with a decent cord, like the ones that Astatic uses. The Superstar DM-507 is my go-to. https://www.ebay.com/itm/3050474478...adANq91JSiEEnz8EGqPJRBloTgEyaVsBoCtoMQAvD_BwE $12.99 + .99 cent shipping.
