NAD 62 6G4-A Super Amp

[øøøøøøø]

Which Weber

The Weber 10A125 is what I put in, they sound super nice and smooth. I must say the reissue Jensen P10Qs also sounded real nice. I have not heard vintage 10" Jensens, nor vintage JBL 10"s (tons of 12" and 15"). I do have a '62 Bandmaster cabinet that has original Oxford 10K5s (I think). I don't really love those! Kinda dry.

10A125 is a GREAT speaker.

One of my favorites all-time... at least the ones I was getting like 10-15 years ago. Reissue Jensen P10Q is definitely good, too.

Vintage 10" Jensens are also great, but many of them (most?) are dead or reconed by now. These things are old and made of paper + glue...

Vintage JBLs are anything but "nice and smooth." "Bright and crisp" if you like them, "harsh and edgy" if you don't.

I love an old Oxford too, in the right circumstance. It really just depends. Most of the old speakers have their uses, and many of the new higher-end ones are also really nice.

Thanks for the suggestions so far!
I have looked up Weber spekers. Turns out they are really expensive over here in the EU. 10A150 is almost 400€, 10A125 close to 300€. Holy crap!
I'll have to find some used ones to try, if I decide to go that route after trying JBLs next week.

yeah, Webers are pretty pricey once you ship them over. Jupiter are supposedly very close to Webers (and I think Hulakat on here is a big fan) and are better prices because they're EU-based.

This is what I have often heard and what I have always found interesting.
I run 15" JBLs in tone ring cabinets and find that the high frequencies are pleasing compared to other 15" speakers in other cabinets (compared for example to Eminece EPS 15C, AlNiCo Jensen 15" in a cab with closed back and tone ring cab). More punch too from tone ring/JBL como as well.

I had an AlNiCo Jensen 15" in a Princeton clone for a short time. I had to seriously turn down the treble and bass to get a balanced and full clean sound. After replacing the Jensen with a JBL D130 (without F) the amp actually became much smoother. Crisp, yes. But the EQ could work as intended.

Similar experience with JBL K120 vs Emince GA-SC64 and Celestion V-type in a 6G3 clone. Again warmer/more pleasant in high frequencies.

I had the 10" JBLs in 63 Vibroverb RI. They sounded great on the normal channel. BUT the bright channel , which is really bright, was harsh and edgy.

I admit that my sample is quite small from a statistical point of view, but this is my experience with old JBL speakers.
My personal conclusion is that it depends on the application.
It's all so subjective and a matter of taste. And that's the beauty of it.

ToDo: check Jupiters Thanks for pointing out this option!

I had a Silverface twin with the orange JBLs and those suckers could extract fillings from 500 yards the bottom end was lovely out of them though, not gonna lie. I can see why they were so popular with pedalsteel and keyboard players, extremely full-range

Great description. Bright amp & JBL = You must apply for a gun license

I’ve got two Celestion Golds in my blonde Twin, which is effectively a bigger version of your Super. I’d absolutely recommend two of the 10” Golds for this.

i’d put any of those 10 or 15 jbls in some of my fender clones i’ve built. they’re so much more expensive than bougie modern speakers here, for a re-cone. forget an original in good shape. definitely agree on the bright channel edginess, however.

most of the re-coned ones i see the seller won’t disclose who did the work, and that makes me wary.

someday.

JBL D120, D130 (etc) recones are not it, as far as I’m concerned.

JBL does not offer recone kits for those models, and hasn’t for decades. So whatever is in there will be random.

I’ve seen all sorts—one popular aftermarket recone kit had a ribbed cone, even.

A proper D130 cone has a curvilinear cone profile (like a trombone bell), no ribs, and an edgewound aluminum voice coil made of stacked ribbon wire (picture a toy slinky—only shorter).

Most aftermarket kits get several of those things wrong. Any one being incorrect is disqualifying to me.

Thanks! I'll have look at frequency response charts of 10" golds. Do they break up easily?

[ziess]

No, you won’t get much breakup out of them. What they will give you though is the most lush, three-dimensional sound. They can take a while to break in but once they do they’re next level.

Celestion golds are great speakers.

If I lived in EU and Webers etc were stupid expensive that’s probably what I’d go with

Here in the US it’s the opposite problem… the golds are about 2x as much as an AlNiCo Weber

[Igorilla]

congrats!! I was after this amp for decades but they’re so expensive. any sound clips? I also vastly prefer solid state rectifiers (especially for surf music).

I built a 6G4 (non -A variant) Super last year with custom iron. It’s so good. thinking about doing an SS rectifier on it.

i think I like alnico 10s on the super. i haven’t matched speakers to mine yet. it also sounds good through a ceramic weber/warehouse combo of 10s.

Update & sound clips

I spent some time yesterday night in my practice room with the amp and then swapped the Oxfords for JBL K110s.
I've recorded only the vibrato channel as the normal channel needs a new V1 tube and I had none with me.

It's just noodling showing some single note lines and chord lines. Only effect is reverb from 6G15 reverb unit.
Guitar: Jazzmaster with 12-52 gauge flatwound strings and Q-Pickups custom 58 PU set.

Unfortunately I forgot to lock the snare which is singing along happily in the background.

Vibrato Channel with JBL K110s (knob settings identical to the test with Oxfords, identical mic placing etc.):

Normally I would turn down the bass a little bit with JBLs, but I decided against it to display the difference between the speaker pairs.

One more update: I'll try to find a used pair of Celestion 10" golds based on recommendations here. I am just curious to try them.

[DeathJag]

You could pop the preamp tube in V1 to play out of the normal channel. Some he-men do that while the amp is on!

Sounds like the Oxfords are a little brighter?!! That's wild, the 12" and 10" oxfords I have are darker than JBLs, and also darker than Jensens. The drips sound great on the oxfords!
