    Hey guys. What info would I need to post to get some help dating my Princeton Reverb?

    As far as I know it's a 1968, but details are a little sketchy.

    I bought it from someone who had bought it used themselves. They said it was a Silverface that had been Blackfaced. But when I took it to a tech, who as far as I know is really knowledgeable, he was pretty sure it was an actual Blackface. But I know the 2 would be similar, so I am not sure how he came up with his conclusion.

    Again, the amp sounds great to me no matter what it is so it doesn't matter a ton. But now that I am not out gigging with my gear I'd like to get something set up for it insurance wise so I am curious about value.

    So ya, let me know what info I would need to post. Thanks.

    If you take the chassis out of the cabinet, sometimes to will see dates written on the inside by the people who assembled the amp. You can also date an amp by the serial #s on the speaker, chassis, or transformers.http://www.provide.net/~cfh/pots.html Check out this site for some info on dating amps and guitars.

    What is the chassis serial number?
    Here is where it is located on the back.

    Serial: A 19218

    Facing the back it's on the far right, and it also has a little "R" scratched in near the serial on the left of the number.

    Transformers:

    022772
    8316751

    022913
    -606-6-2

    022921
    8316726

    Those are all the numbers I can find. Thanks for any info.

    Serial: A19218 = A18900 to A21500 - 1968

    Transformers:
    022772
    8316751 = EIA code 831 Better Coil & Transformer: 1967, 51st week

    022913
    -606-6-2 = 606 Schumacher/Woodward Transformers, Chokes (missing a digit for the date)

    022921
    8316726 = EIA code 831 Better Coil & Transformer: 1967, 26th week

    Here is a list of the EIA codes.
    http://www.ampwares.com/ffg/eia-codes.html

    This amp should have had a silver face plate (early 68 had some thin vertical black lines) and a silver "drip rail" around the grill cloth. The circuit was most likely identical to earlier blackface years as they did not mess with the smaller amps much and this is the forst year of the silverface anf the changes were mostly cosmetic.

    You can see the silver trim on my 68 Dual Showman Reverb on the left.

    Oh ya... When I take my Princeton Reverb on a date we usually have a couple of beers and then I make it squeal and howl a little before breakup...

    Thanks Big Mike. That is what I figured, and it's what the seller told me.

    The cabinet actually fell victim to UPS back when I got this amp. They paid for a replacement though with no hassles. It's in an Allen 12'" cabinet right now.

    Yeah, a 1968 SF Princeton Reverb oughta be identical under the hood to a 1967 BF one. They didn't bother changing the smaller amps until a few years later...

    Cheers, Tim

    Do you know about then this happened Tim? I've got a '70 PR and I wondered if it's the BF specs.

    I just went to the Fender Amp Field Guide, and it looks like there was some kind of circuit change in 1968 (the circuit name changed from AA1164 to AB868) and another (probably when they changed the rectifier tube) in 1970 (AB1270), but as far as I know, the only siginificant change was in 1977 or so when they added the pull-boost.

    Cheers, Tim

    Here it is with it's black faceplate and Allen cabinet by the way:

    Obviously not a collectors amp like this, but I find it way more functional for my needs with the 12" speaker and larger cabinet.

    Oh ya, here is that missing number Big Mike. It should have read:

    022913
    -606-6-25

    I take it from the dates on the parts that this amp was likely produced very early in 1968?

    YourTransformer looks like the 25th week of 66... or else a replacement from 76.. but most likely a 66.

    Do you still have the original faceplate? Sad that UPS damaged it. Unfortunately the reduction in overall value is greater than the cost of the replacement cabinet.

    The cabinet does not need to be taller for a 12" speaker. I have a 74 SFPR and the previous owner enlarged the hole in the baffle and installed a 12" speaker. It had a Peavey Black widow in it when I bought it and it was too heavy and clean. I replaced it with a Fender/eminence and may eventually put in a weber. In my opinion the PR is the near perfect small amp. I like the early silverface Fender amps (pre MV, PrePull Boost models).

    Charlie, Does your friends sister have any Telecasters or Fender amps? Has she ever bought a telecaster for anyone? Can she play drums without speeding up? Can she play bass without playing too much or maybe blow harp and sing? Or... Does she have a Harley or pickup truck and a big screen TV? These are very important questions... if you really want help.

    Big Mike, I have tried a normal sized PR with a 12" speaker in it. It's just my opinion, but I think the slightly larger cab makes the amp sound even better. I love it.

    The thing is with this PR, I got it for a pretty good price in the first place. And I bought it for it's functionality, not it's 'collectors value'.

    This is the faceplate it came with.

    The UPS story is kinda interesting. I paid $500 + shipping for the amp. the box arrived and it was just mangled. The cabinet was a mess (broken wood, tolex tears), and the reverb tank was broken. The seller had it packed at a UPS store and they did a brutal job. I got the the amp repaired, but the cabinet would have needed some SERIOUS work. So I ordered a new cabinet, and the seller sent all the bills to UPS. UPS covered all the repairs, paid for the new cabinet, and refunded the shipping.

    I sold the damaged cabinet some time later to someone who wanted to work on it. I know I should have kept it for collectors value, but it was never going to be in my budget to fix it, and again the amp sounds and looks great in it's new cab.

    So basically when the fiasco was all done, I actually paid a fair amount less for the amp then the original asking price. And looking at it from the perspective, if I ever did try to sell it, I'd likely still make some money even as it is.
