The mic also came with a word of caution....
|Don't test a ribbon mic with a multi-meter or else...|
I am particularly pleased to see the warning not to use a DC meter on these. Quite often I come across ebay auctions where the seller measures ribbon mics with a multimeter, unaware that the carrier current can bump the ribbon out of the magnetic field and stretch it. :(
Grampian also made matching transformers for their mics - we have a few available for sale. Here is the factory drawing for the transformer.

I posted some other Grampian documents last November.
Many thanks to Pete Guppy for sending this in.
