FDP Forum / Fender Amps: Vintage (before 1985) / Help me identify this Princeton Reverb Amp

I bought a PR amp about 6-7 years ago from a friend at school, and don't know much about it. It looks well worn and I know that it's definately not original because someone replaced the speaker with a cheesy radioshack one. I've been wanting to fix/ restore the amp, but cannot find out much about this one.

Serial number is A19391, it has a silver faceplate, but RED lettering that says "PRINCETON REVERB AMP". Most of the PR's that I have seen pictures of have the blue/green lettering... is this faceplate not original as well?

See pictures below (link) updated in 2018

Is there a QA sticker on the back with a datecode?

Do you mean the tube chart? It is not there anymore, I think the person who changed out the speaker (and the tubes) also must have removed the tube chart.

There is a number 69 that is underneath the circle with the "underwriter's seal" on the back panel.

Thanks so far...

Never seen nor heard of such!

A "Red Letter" Princeton Reverb?

There were Bronco amps with the red lettering - but this is a new one to me - and it looks legit -the blacklines, cabinet construction, "snowman" 8's,

upper rear panel is wrong but most looks legit.

Thanks, I'm begining to wonder if someone bought the cabinet and some of the other parts and threw it together themselves?



Dec 3rd, 2007 06:33 PM   Edit   Profile  

No, it's just the upper back panel and screws/washers that don't appear to be original to the amp. That's a rare one!! Never saw and knew about a red letter PR!

The back panel looks like some of the '68s on ebay, link below. I'm new to this, but what's different looking on the back?

Thanks for all the help so far...

Look for an inkstamped code on the bottom of the chassis, that would help, some.



Dec 3rd, 2007 06:38 PM   Edit   Profile  

The upper back panel should have shoulders that would be somewhat U shaped that would cover the upper corners. Also the early '68 late '67 amp back panel screws didn't have washers.

Rocky, thanks
Csharp, i'll look for that code, but i'm gonna take off tonight, will get back to you later tonight or tomorrow.

Next question is, who can I take this to in Southern CA to get the work done on it?

Must have been some kind of limited run. It looks like an original faceplate except for the color. Blackline too. It looks like a '67 or '68.

wow lau70!
that´s amp looks totally straight - and it seems you´ve got a very rare amp there!
it looks like a factory "mongrel" from ´68 - which makes sense in so far as the red-lettered "bronco" came out around the same time - so maybe they just tried a couple of other faceplates in red.

and yes, the back-panels "might" have been replaced with later ones - in the late 70´s these amps came with 2 straight panels AND washers on the screws.

a classic amp and well worth a little effort and TLC to get it back to shape!

cheers - C.

Everyone, thanks for all the great help so far.

I'm getting pretty excited about learning even more and then getting around to fixing it back up.

I'm guessing that the radioshack speaker and GE tubes aren't the best components for the amp... Since i'm new to this, what would you guys recommend for replacements, and are replacing these items a do it yourself kind of job?

also, Csharp, I coudn't find the inkstamped code-do you have an example of what I should be looking for?

You wanna trade your "defective" red ink face plate for a properly manufactured blue ink faceplate? ;-)

I miss my Bronco...

edited to add: Don't dismiss the GE tubes. While they aren't thought of as highly as RCA, they are still USA manufactured tubes, and better than any glass being manufactured these days. Evaluate them on a tube-by-tube basis.

"You wanna trade your "defective" red ink face plate for a properly manufactured blue ink faceplate? ;-)"

I'm guessing that I should probably hold on to this amp for now ;-).

I'll have to do some detective work and take some pictures and post descriptions of the tubes. If you don't mind, maybe you can tell me what i've got...

That's the only one I've seen. That is for sure a rare bird but it does look legit.

I think you have a very rare amp there. Keep this thread alive with any news you get on it. Send someone like Vintagejon pictures of the chassis and ask him if it is any different from the normal SFPR. This thing could be worth quite a bit more than a standard SF but if I were you I would not sell it.
