    I don't know. I'm not after super clean. Far from it.

    The magic of these is in the subversion of intent.

    There is breakup in a Super even at 3-4 when it sounds "clean". Take that away, the accompanying compression and the way frequencies get suppressed and then leap out? Is it still a Super?

    Might be a cool amp for someone. I don't know. But if clean is desired, grab a JC40 and be done. (It's own cool sound, in my book, FWIW).

    Cool.
    Yeah, I learned, (as a former disbeliever), that tranny size alone can make a huge difference. I took my hot rod Princeton back to stock Princeton a year or two ago. However the chassis had been hacked for the big PT and at the last minute I just left the Super power tranny in the amp. It absolutely floored me how much cleaner the Princeton was with that change. I have only been able to use a PR in very small clubs with limited low gain OD in front before. This thing stays fairly clean up more on the dial.

    I accidentally built a clean 5E3.

    There was one down at Crossroads Guitars I'd visit once a year. They usually had a cool amp or two down there. Year in and year out, that was one of them. They didn't sell it because it was overpriced. It was overpriced because they didn't want to sell it. They didn't want to sell it because it was a unicorn, a 5E3 that played clean.

    I figured I'd get a look under the hood some day. Since they moved out to Salt Lake... probably not.

    No worries. I built my own.

    Don't forget to decouple the tremolo with a switch on the pot. Better fidelity.

    Still trying to wrap my brain around playing a Super Reverb full out.
    I've got two of them a '73 and a '66. Guy I bought the 66 from played it on 7. From experience I knew something was fishy because he lives in town with neighbors 50 feet on both sides.
    Back home the '66 on 10 is about as loud as the '73 on 3 or so. Still need to service that amp, been sitting in the corner a year now.

    Anyway if he played healthy Super Reverbs cranked, where did he play them? I'm in the country but have neighbors a quarter mile away that probably wouldn't like that.
    Something is wrong with his story, maybe he's using an attenuator or turns down the guitar volume? If he gigs where?
    And besides that the stock speakers in an old SR would blow in short order like that.
    Can he still hear? :)

    Loud is really more a function of speaker efficiency than anything else.

    Actually tube jockey, tremolo disconnect gives you more gain, which can be taken as more fidelity. For some songs, I like the tremolo disconnect. I put a switchable pot on my tremolo on a 74 twin I am rebuilding.

    Also, not actually a mod, you could slightly bias the amp slightly colder for cleaner sound. Too much coldness on the bias can make the amp lack harmonics and sound a little sterile. For amps you want to be cleaner longer, you could order a matched set of tubes that have a the least amount breakup. The current production tubes I really like are from “The Tube Store” their preferred series 6l6GC aver very similar to the RCA blackplates. I buy these a lot, since they are not too expensive and sound great in my Fender amps. I think they are just slightly nicer than the TAD 6L6GC. I didn’t care for their 6L6WGC for the super reverb, that was initially recommended.

    I
    m thinking about a Heyboer with HV secondary 352-0-352@250ma. Enough?
    I wasn’t able to find reliable specs on what the current capacity on the original was. I saw anywhere from 200-250ma.
    I’ll be using solid state.
    Thanks! And yes I’m putting it in a Princeton chassis, may have a handle on a JBL E-120-8.

    The tremolo circuit is not going to be built

    It would be simpler to build a straight Twin clone with traditional cab. But the whole thing here is what he wants, and it’s not a Twin. He wants as close as he can get to its clean, in a small amp he can manage alone.
    He wants:
    1. Twin reverb clean
    2. Super Reverb wattage
    3. Smaller Princeton-size cab with a single 12.

    I thought going with a Super Reverb AB763 circuit to start with was a good start. Just looking for suggestions on cleaning it up. Thanks though

    12AY7 tube on the front end. Lots of filtering. Big iron.

    Thought you said that weight was an issue! JBL E120-8s weigh in about 23 lb, tone to kill/die for but heavy as hell!

    Thanks. Can you school me a bit on this as it’s an area that I haven’t delved into yet. Thanks,

    Ted

    Yeah, I know super heavy but in the smaller size maybe less awkward?

    I also have access last to an Eminence Classic Lead 80 that might do in a pinch if the JBL thing is too much. Supposedly very efficient and clean speaker.

    I bought an E120 on evilbay several years ago. I had a cabinet made for a PRRI I had, and installed the E120. Great sound, and with the Princeton chassis, the weight wasn't TOO bad, but the weight of the speaker created rattles in the cabinet. I took it out of that application, and put it in a Blues Deluxe Reissue. The 40 watt vs 15 watt input really opened up the sound of the E120,but I think the larger cabinet of the BDRI was a significant contributor as well.
    My main amp these days is a 1971 DR, modified to run 6l6s with a solid state rectifier, and 2x10 JBL D110Fs. I don't play quite as loud as your friend, but the clean factor of that DR is impressive. _526.JPG _527.JPG

    Thanks.

    I’ll be building the cab for this one too. I’m used to building 15w combo cabs in pine so I’ll do my best to beef this one up as much as possible.
    Pine ok? Or rigid/heavier like BB ply?

    Pine would save weight, the cab I had made was plywood, but the guy that built it talked a better game than he delivered. I suspect you'd do a better job of it. The problem was more baffle buzz that cabinet, so with the E120, making sure the baffle is REALLY secured to the cab. I finally had to resort to using weather stripping between the cabinet cleats and the baffle board- worked!
