Does this look like a bias adjustment pot?

This is a silverface Princeton, which should have a nonadjustable bias. I took this in for service a few years back and I'm wondering if they installed an adjustment pot. I did tell them I wished the tremolo was stronger, so I'm wondering if this pot is for bias, tremolo, or both, since it's a bias tremolo?

It is a bias pot. There are many bias pots that are small like this even on mass produced amplifiers. The Princeton Reverb has stronger tremolo when running a cooler bias. I suppose you could look at it as both a bias pot and trem pot but... it is a bias pot.

Thanks. To be clear it's just a Princeton. I wish it was a Princeton Reverb!
