    Hey guys,

    Just scored a '63 Princeton. Couldnt wean myself from it all day! Great tone and stunning tremolo.

    I'm taking it to my tech to set it up for 220v, and most likely get a cap job.

    I'm thinking of changing the speaker. It has a CTS, which I think is original. Is it worth it to install a new baffle board and go for a 12"? Will this make the amp sound boxier? I kinda like the punchiness of the 10", but need a bit more volume.

    Any speaker recommendations?

    Cheers,
    Teleka

    Get all the electolytics replaced then try the speaker. You might like it. You might not too but try it first.

    My 64 Princeton Reverb has a 74 CTS alnico I'll probably never change it. Before the cap job the speaker sounded "farty."

    Speaking of which can you post a picture of your CTS? That'll help find out if it'd original be sure to get any codes in the shot as well.

    How do you set it up for 220v from 110v? Change the power transformer? What makes you think it needs a cap job? My take is, if you love the amp, and just want more volume, mic it. I would be concerned about removing some (or a lot) of what you love about the amp, making these changes. I think I remember MuchXS commenting one time about how many perfectly good working vintage amps were ruined by swapping out components that had drifted out of tolerance slightly, not causing any harm to the amp, and ultimately giving it that magical tone. I'm not superstitious, but I don't think I would swap anything on that amp if it's working and sounding good.

    That makes sense, thanks.

    Here's a shot of the speaker

    Congratulations on getting a killer amp. I built a clone, and it's really great, I can only imagine how much better a real one is. Enjoy.

    That is the correct speaker, ime. RE: electrolytic capacitors....these are not the components that can be ignored, ime. They need to be replaced.....according to that speaker the amp is now 52 years old....date code reads the 47th week of 1962, so I'll take it that the amp is a '63....tube chart should be stamped M_.....some month in 1963...M + 1963.
    Other components like tone or coupling caps and resistors need not be replaced unless they have failed or drifted way out of spec. (;^)

    Congrats on the new amp, just scored one a few days ago. Yours looks in much better shape than mine. :)

    If you do find you want to upgrade the speaker for more volume there's plenty of 10s that'll do that. Something like a Red Fang 10" is 102.db. Going from the old CTS to something like that will knock you on your butt volume wise.
    (not saying that's the one to go with it could be IDK)

    I think Celestion also has some 10" in the 100 DB range.
    Replaced a 53 year old Jensen C12R in a 62 Reveberocket with a G12H30. It sounded good but the volume increase was so much I had to run the amp turned down to where it was clean and boring.
    Little amps are only fun of you can crank them past 5.

    But the way a 6G2 was my first amp in like 1980. Sounded great but back then a Princeton was like a fat chick.
    OK in the bedroom buy you don't want your friends to find out about it.:lol:

    Here is a question RE speakers, which speaker would have the most brightness? After something that I can use for dark guitars.

    IME, considering a speaker change while running on old electrolytics is......in the words of another era....putting the cart in front of the horse. (;^). YMMV........but ime a 6g2 is not a dark amp that needs a bright speaker in order to accommodate any guitar. If you do want a bright speaker, a modern Celestion G10 is a bright one......I have no use for them....but they are bright!

    Thanks for the replies. For the time being I'll just swap the electrolytes . Might keep the speaker, so I can crank the amp at a reasonable level, and get an external cab if I need more volume

    Well, you brought your old thread back up. What has transpired with the amp?

    I changed the original power tubes and sent it to the tech to swap the electrolytics. The original speaker is still in. When playing with the band I run it through a 2x12 cab, but being a six-piece with a heavy handed drummer it needs to go through the PA.

    It's a terrific amp. My only regret is not having tried one earlier!!

    Good call on the extension cab. My comment was going to be, don't put a 12" in it. A 12" in a bigger, deeper cab is a better idea. Much better sound than stuffing a 12" into the smaller original sized combo cab. In my experience.

    If you ever decide to go to an export (220 V ) transformer and are willing to sell the original power transformer please PM me. I have been looking for a 125P1A for a while. I would be willing to buy and ship a mercury magnetics 220V mains transformer too you plus cash.
