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! Pics for reference:

Unfortunately, Mr. McCurdy passed away some years ago. He used to send out scans of schematics for a small fee. Unless someone has previously sought this one out, you are not likely to find it.

darn thats too bad, will have to go the reverse engineering route I suppose! Thanks for the info!
 
You know the CBC had all this info at one point, may still yet.

That thing is more the scale of a monitor or program amp.
Yea that would make sense this particular one belongs to a local radio station here in Halifax called ckdu I imagine they most likely acquired it as a hand me down from cbc but I have no idea about who to contact etc. lol might be lost to history
