    Unusual Dynacos

    I didn't get very far either when searching for USS. I do recall that this same tweeter was used by other manufacturers, including, I think, McIntosh. Anyone who felt shortchanged by owning this American-made A-25 need not feel bad as it sounds great, even without the Seas drivers. I've never confirmed this, but I think these same drivers were used in at least some A-25VWs which were the cheaper, vinyl-clad version, that were introduced after the original A-25 became very popular. They were not as elegant with vinyl cabinets & dark grill cloth, but they sounded great & were priced to compete with AR 4x, AR 7 & KLH 17, all formidable competitors, but IMO, no match for the A-25. Most A-25VWs I've seen used a very different-looking tweeter that had an orange-colored dome. I bet these 2 tweeters were otherwise very similar.

    EPI 100 Restoration

    Thanks for a great restoration post on a great speaker that doesn't get enough recognition.

    KLH Model Twenty

    Nice work! Has anyone actually measured the impedance of a KLH 20 to see if it is different from that of a 17? Perhaps the woofers are different even though they look the same.
  4. Very nice job. Your ingenuity & creativity are admirable.
  5. They're not Corals & they have absolutely nothing in common with any ARs or M&Ks.
  6. Thanks for this recommendation, Kent. I think I'll try it, too.
  7. Love your vivid recollections, Frank. NYC in the '60s was hi-fi paradise. As for the mystery speakers, they are either homemade as Frank suggests or more likely, could have been bought inexpensively as ready-made at one of the many small, less-exclusive, hi-fi/electronics shops that were all over the place back then. The Calrad-branded crossover is the tipoff: Calrad distributed inexpensive, usually Japanese, parts and finished products including small speaker systems, small hi-fi amplifiers, microphones, PA system components, etc. Calrad products were widely sold by small electronics shops including Gem electronics in the NY Metro area, a favorite haunt of mine as a kid.
  8. AustinJoeC: Yes, that "protective mesh" was not very protective. I have never succeeded in adequately repairing the damage done once it's been pushed in. All tweeters I've heard in that condition distort, sometimes badly, even after attempts to repair. You seem on the right track, but your biggest problem will not be with the speakers themselves, but will be with insufficient amplifier power, assuming that you will want to play them loud. Remember that you often can cause more damage with too little power rather than with too much and the resulting distortion can be hard on your tweeters. You might consider using appropriate fuse protection. The stacked Advent idea was a response to the already-popular practice of stacking Dynaco A-series loudspeakers. Dynaco included a detailed stacking instruction sheet with every pair. A very important difference was that the impedance of two Dynas in parallel never dipped low enough to cause trouble. Not so with Advents! FWIW, I've been using stacked Dynas since 1970 and have never had any problems except for complaints from neighbors.
  9. Great film! Not sure we've progressed much in 60 years. Loved the Garrard 301 & Quad pramps.

    A25 caps

    It seems like Dynaco used good quality caps that last a long time.
  11. Interesting, tricky nomenclature as they are neither Fives nor Twelves.
  12. Anyone know if Walter Berry is still around? I'm sure he'd have some good stories to tell. He was always very kind to, & tolerant of, a certain teenager I know who regularly visited the NY showroom with an armfull of LPs.
  13. Yes. Check the pot to see if it's actually working. Rectilinear pots were notoriously flimsy compared to AR, et. al. The caps are likely bad as well. I had to replace both a burned-out pot & dried-out cap to get my Xs going. Check or replace the caps first-it's easier & cheaper.

    Rectilinear XI

    I love the fact that you're using Rectilinear XIs instead of your Vienna Haydns which probably cost 10x as much & probably don't sound 1x as good! I had a pair of very good Vienna Mozart Grands sitting next to my Rectilinear IIIs. I sold the Mozarts & kept the IIIs.
  15. This is what an A40XL crossover looks like. I've owned these for 40 years & have never opened them up. Figured somebody, somewhere may be curious, although these are rarely seen. Sounds like an A25 with extended high end and with greater efficiency & power handling capacity. Just replaced the cap & like what I hear very much.
