No, here has no production models, and seems to be arriving in this morning.
Actually I can see 3 protos here but they are differing in several points from the finals.

Glad to hear that, and should be S/N 075.
The other one (S/N 003) will arrive here with mine, and immediately modded and shipped to you

No, you can use OPA637s on this amp
What I told you before was for your P3+.
However some limitations are existing, easy to say.....
DO NOT connect JP1 and JP2, and DO NOT use with low gain position.
When the jumpers were connected, 637s will supply
huge DC to your treasures
And this circuit can make 637s without oscillation at Low gain, but I can't assure it as 100%
