I read before in a number of places that the Princeton Reverb tremolo is better than the Deluxe Reverb tremolo (thinking of the reissue models here). I just tested the two (reissue models) side by side in a store and can say that the Deluxe tremolo was more intense and perhaps a little more "raw" (?) than the Princeton one but it seems when holding back on the intensity on the Deluxe a fairly similar tone can be obtained between the two.

Anyone who know both well can comment on this? I read they are slightly different circuits.

They are totally different circuits. The PR trem system actually varies the bias voltage of the power tubes, while the DR relies on an opto-isolator oscillator to gate the pre-amp signal on and off at specific intervals prior to the amp's phase-inverter stage. The latter system was the first of three tremolo effects developed by Leo.

I see. I guess the difference in the end result between the two and which might be "better" is down to a matter of taste. I can't really decide from the short test I did which one I prefer. I wanted to like the Princeton more because I like the more compact cabinet as well.

Yep,TC5A. You're spot-on! It's a matter of taste and consideration of the entire amp. JMO Art

I would go with the PR but my main motivation is the cabinet size and slightly better portability.

My ultimate amp would be the vibrato channel of a DR in a PR cabinet with a quality 12" speaker...in Brownface cosmetics.

Yes that is about what looks to be the exact choice I would make (in blackface though). The Deluxe Reverb tremolo seems more intense, so going lighter on the depth should be able to get similar results as on the Princeton.

It looks like they can do something very close:

Princeton amps, point to point, 12 inch speakers, with additional mid control. Maybe they can put in a DR tremolo instead of the Princeton one?

I would still be interested to hear from people who know both the DR and PR well which tremolo they prefer and how they characterize each. I haven't spent enough time with them to really have a definite preference.

From my experience with BF and SF DR and PR's... the DR has a stronger tremolo/vibrato effect than most PR's. But, the PR tend to be more sensitive to adjustment and the effect (though subtle), starts sooner on the dial. One thing for sure. The tremolo/vibrato of the PR benefits from a strong bias supply. New cap really helps.

This site may help, a bit (with phase shift & tremolo effect):

I like how the valve wizard calls the supply voltage HT (High Tension). 8)
