I am on the hunt for the schematics for a Mccurdy Ad 975, it looks to be some transformer balanced input preamp but there is absolutely nothing online, I would be happy to even purchase something from them/anybody but have not had any luck getting in touch as their number seems to be defunct etc. If anyone has a contact please let me know!
