What Princeton mods do I have here?

Hi folks, I am at a point where I need to shrink my stockpile of amps. I have too many cool ones, and want to bring two more out of storage! But, I don't really need them, and don't have room, plus, they don't get used that often.

To help facilitate this move, I am looking at my Princeton Reverb.
Should I keep it?

It's a 70's model with a BF panel and grillcloth. But..........
Here's a list of the mods someone did or had done.

1. Mid control dial in rear (great )
2. Reverb dwell pot (I leave it on full) New Acc. rev. 3 spring pan.
3. No stock spkr.
4. Very little volume til turned up to 7, then it's fine up to 10
5. Should there be a choke (small transformer) between pre-amp tubes V2 and V3? (Reverb???)
6. Tube chart had the 6v6's crossed out, and 6L6's penciled in. Spring clips were stretched as if larger tubes had been in use. I bought it with 6V6's in it.
7. Power trans. is large. Chassis is modded to allow the larger PT.
8. It appears to have 2 OT's. One smaller, one larger. I didn't look to see if they are both hooked up.

Caps look newer ??

Basically, is this a (modded) monster amp that could be beefed up with 6L6's once again? I bought it for a good price, but is it worth keeping and stepping it up with relative ease?

I have pictures of the transformers. Maybe someone could help in identifying them. The numerical codes are readable.

Just wondering what to do with this puppy?? It DOES sound good !! but as it is with the 6V6's, it's a little underpowered for my gigs.

Thanks in advance.

Yeah... bring on the pix. I won't be responding with answers... but those capable of responding to your query need to see pix.

Hard to tell from the partial chassis shots but it looks like a Princeton reverb with larger transformers at the OT and choke. You can look up those transformer codes to see what they are. A couple good shots of the other side of the chassis would detail and explain any other mods.

Not the first "modded for 6L6" Princeton I've seen. The other sounded glorious w/6L6s.

Considering how heavily modded this amp is, it likely has a good deal more utility value than resale value. I'd get it evaluated by a tech, maybe try some 6L6s to see if that gets you the bump in power you need (if not, maybe a more efficient speaker).

Remember that Randall Smith of Mesa Boogie fame used to beef these little amps up... but for me 12 watts is plenty from them... might be a good gigger when all checked out

I had the amp evaluated by a guy who specialises in Fender repairs in the Buffalo area. Great guy, very thorough, knows his stuff, and really cares about the product. Frank Zuco, if I have the last name correct!

The amp has a lot of mods for sure, and some of dubious quality, but it has been working fine for me for years.

The OT is a Bandmaster/Vibrolux at 4 ohms. He put in 6L6's that don't draw too much current and biased it for L6's or V6's, repaired some solder joints and cleaned sockets and pots.

It sounds fat and full now. Should be louder at gigs !!!!!! Let's hope.

awesome... would still love to see the circuit board side if the chassis.

I will get to that photo. The tech also said, the PT was larger than stock, but maybe not big enough for 6L6's, but didn't think it a problem, since the stock PT was like a Champ's !!
(not great for a 2 6V6 amp)

Any opinions on that?

Next I will need a great 10 in. spkr. at 4 ohms since the modder probably had a 2-10 or 12" cab in mind

My princeton has a D110 which could certainly handle the added wattage of the 2 6L6's... but it mostly sits on top of a 1x15 with a D130. It's just so much bigger sounding. The Weber Neo sounds pretty nasely in that cab (but sounds great in the vibrolux).
