RE: 12ax7 for ARC SP16

Recently found a 12AX7 that one would not think would be all that special, BUT, in fact, it's one of the best performers I've herad.

Found a stash of Japan 12AX7 (14 mm) plates that are marked Raytheon Military with a 64 date code. These are amanzing, very low microphonics, very low noise, balanced sections, and one of the most neutural tonal balances I've ever herad. They look like a Mullard clone, but they could also be a Raytheon clone, as I've one pair from 63 marked Raytheon USA that perform the same.

Also found a stash of Japan 12AU7's that are either marked Daystrom or Baldwin. They are 17 mm plates, and look to be a Mullard clone. Same type of perfromance, low noise, microphonics, matched sections, etc. These are also great perfromers.

The Japanese tubes from the 60's seem to be as good as the US/Euro tubes they copy. Thanks to what appears to be high quality control, there is a high probability they will perform well.

Lastly, noticed the Japan tubes from the 60's flashing looks like the US/Euro tubes, in that they silver vs. carmel colored.
