    Fender Princeton Reverb 1980

    Received the amp last Wednesday, turned on and flop!, blown fuse...:confused:
    It was a bad 6V6 and also a bad 5U4.
    While waiting for new tubes I‘ve cleaned the cabinet, swapped the speaker and checked for visible flaws:

    The 40 year old Princeton looks after reassembling pretty near mint. It‘s clean with a nice vintage patina and the typical smell only old Fender amps got! And again- the last Princetons got a Blackface frontplate until 1981 and the circuit is the old B1270.

    Today I put the new tubes in and- WOW:
    That amp sounds amazing!
    Superbly tight basses and silky shiny highs, totally warm Fender 60’s clean, a really perfect Blackface tone! The Tremolo is a bit weak (I guess that’s a common issue on old Princetons) but nevertheless nice and organic. The Reverb is the best I‘ve heard since years!

    Compared to the 65 Reissue it sounds much more organic, warmer and with complexer and richer overtones. The reissue sounds good, but the original sounds great: One of the best clean tones I‘ve heard, maybe the best!
    Another good thing: the amp is real quite, no strange noises, no hum, no nothing!

    I‘m sure the Alessandro speaker is a pretty good choice for the Princeton and it will be even better after 30-50 hours of playing.
    Only strange thing- that Princeton is incredibly loud. Volume on 2 is like 4 on the reissue!

    I‘m deeply impressed!

    Outstanding, congratulations! And so clean looking. This is the amp I could retire with.

    PR’s are my weakness. I want at least 10 more. That is one beautiful amp. Perfection in my book. It’s rare to find one that nice.

    A weak trem can be a bias issue, but if that checks out a simple cap swas can sort it out.

    The trem on mine is a little weak too, but I don't really mind.

    Thought that too. I‘ve swapped the 6V6 without controlling the bias since I‘m not able to do this by myself :eek:
    I hope this won‘t harm the amp until a tech have a look...

    Makes me wonder that the amp is that loud! Maybe it needs a different volume pot? But I guess I‘ll have a bit of time before I‘ll take it to a service since I can‘t recognize anything wrong.
    Atm I use a simple voltage reducer for our 230Volts (only 100 watt consumption). I guess I‘ll keep the original transformer since it sounds so good and order a correct 300 watt step down transformer from TAD.

    This one looks as if it's had the Stokes mod carried out. Note the red wire is the lower left corner of the board, connected to the resistor and white wire that goes to the cap can. That's non-standard, and usually part of the Stokes mod to give more headroom, normally carried out in conjunction with up-rated transformers. The jury is still out regarding the mod with stock transformers, as the standard OT is a little small for the job.

    Thanks a lot. Since I‘m a caveman when it comes to electronics: is that easy to put down to standard?

    It's only a couple of wires, any competent tec can do it in minutes.

    Wow, that thing is CLEAN!
    I wouldn't do the Stokes mod or the other popular mod converting to a long-tailed pair phase inverter. A PR is a PR, why try to make it something else? I have tried those mods a few times and I always come back to stock circuit. Maybe that's just because I have other 2 x 6V6 amps, BFDR, BFD etc and dont need another amp similar to them. And the Stokes Mod wants to give you more headroom similar to a Deluxe. The long-tailed pair phase inverter pretty much makes it a Deluxe changing it from a great low volume or recording amp to a louder cleaner one.

    Absolutely my intention too. Volume on 4 is far too loud for my bedroom that way and it‘s still clean as the amp looks. I would prefer more breakup and less volume, but this clean is wonderful.
