Tested and working well.

Obviously has been painted black some years ago, but could definitely be wiped clean.

Sounds actually one of the better 664's I've heard! We're talking in the minutia, but yes, this one sounds very strong and hot.

It takes an old style Amphenol connector, which is readily available to get. A better option than converting with an XLR pigtail in my opinion, although I have done that to these in the past and it works just as well. Easy to do.
