Electrokinetix Opamp

I figure if anyone knows anything about this, it'll be you guys.

I picked up an Electrokinetix OA-829B discrete opamp. I've read that some of the solid state Pultecs used the 828A interchangeably with the 2520. I haven't done any testing on this one yet, just wondering if anyone has any knowledge of or experience with the 829B and can tell me anything about it.

Thanks in advance.

Came across an Instragram post where these are briefly mentioned. Poster says this specific model (829B) was used in the later Pultecs, and it's the only gear he's ever seen them in.
