    I have a '68 drip-edge princeton amp and I'm worried about pushing it beyond it's limits. Gigs are starting to happen in bigger clubs. Last one I had my monitors cranked because I couldn't hear the Princeton too well. I had it on about 8 or 9. I'm worried about running the amp that high all the time and I'm also worried about the speaker because it's an original.

    It will be fine. Crank it up. It was made to. The power tubes may wear out sooner than if you played it at lower volume.
    Carry a spare matched set in case needed. Is it an original '68 or a '68 CPR? 68 CPR The speaker was made to handle the power. If you like dirt then give 'er.
    If it is an original speaker, it's probably already done in.

    It's vintage. I might take it to get checked out, see what's all been done to it. Other than a three-prong cord, I'm not certain what's all going in there. Sure sounds good though.

    What else matters?

    Just drive the S out of it, and have whatever with you as a backup for gigs.

    If it's never been serviced - for if you don't know FOR SURE - you are taking a big chance. It should be looked at by a qualified tech asap before you end up with VERY expensive repairs. And I would remove the stock speaker...which loses quite a bit of power handling over time - save it, and install a good sub for gig use.

    Have it serviced and checked if you never have, then play the snot out of it. Tube amps are meant to be pushed.

    Service it ASAP - a blown tube, shorted cap, etc...can all smoke a tranny.

    Just to offer up another idea, have a copy of your vintage one made and take that one gigging. Then you don't have to worry about damage, loss/theft, blown speakers, etc.

    +1 on the recommendations to have it thoroughly inspected and given a clean bill of health. A blown filter, bias cap, or smoked power tube grid resistor can wreak a lot of havoc in a tube amp. Once that's done, no worries.

    If the speaker is original, I'd switch it for something about 25-30 watts, new and more efficient, which should make it louder to boot. Keep the original speaker safe if you ever sell the amp. Same with the tubes, if they are original as well. Fender skimped on speaker power handling on the "student" models.

    Depending on where you are, Jim Foote at Music Works in Lawndale (especially for Fenders and Marshalls) or Don Butler out in the San Fernando Valley (a Vox specialist but great on everything).

    Both are superb. And both are buried in work, so plan on at least a 3-4 week lead time unless you get VERY lucky. The techs who can turn them around in a couple days on a regular basis are ones to avoid.

    But as this is actually a simple full-service job and a speaker replacement (save the original in case you ever sell the amp) it's a pretty quick job, and sometimes Jim or Don will knock these out in a week or so. IF you get lucky.

    Neither is always Mr. Personality, and have little time for chit-chat - just tell them you don't think the amp has ever been serviced, and buy a speaker and bring it with you (I suggest something from Weber or Warehouse Guitar Speakers), tell them precisely what type of music you play and that you crank the amp - otherwise they do a "middle of the road voicing and bias setup which may not fit well with what you do. Provide as much detail in a short time as possible.

    Yep get you a new speaker. Jupiter or Alltone 1040 will probably gain you about 3-4db, that'll be like 20% increase in volume. Then get her serviced and tuned up.

    The amp can handle it if it's in good condition, make sure you have good tubes and it probably replace the filter cap can. I think a higher wattage speaker would be a good idea if you're pushing the amp hard. I stuck a Copperhead in mine and I think that was a big improvement. I don't push my amp very hard since I mostly play Jazz at lower volumes. You might think about getting a Deluxe Reverb if you're always pushing the amp hard.
