This is a 25k ohm pot part number 952B "made in japan".I think these are the black beauty model. If you send me an email address I will shoot you over some pictures of them.

They may be. Someone may have swapped them out. I though Precision Fidelity went out of business in the 80's. Maybe not. These were pretty high dolar pots for a mass produced item anyway. Most have a 3 dollar pot, not a 30 dollar.
One way to check the BB is the size, they are 40 mm square. I have a stereo one up in the attic, need to look at it.
The pot should be a log, and 25K is low for a tube preamp. Most tube preamps have a 50K or 100K. Reason is the loading on the phono stage. Most tube phono stages like a high load. Have a Croft Epoch that uses 1 meg pots. Thank is an extreme example.
