fromthebeginning, are you the same person as Northern California Collector?
In any case, I'm doing a study of the production of the 6G2/6G2A. I'm collecting all information of original speakers, serial numbers, tube chart date codes and production numbers.
I find, especially in 1962, that Fender used a variant of the regular Oxford that looks like it has an AlNiCo magnet, and its designation is 10JB-14. There have been three amps for sale on eBay in the last three weeks with this speaker, contact me if you want the URLs. I've e-talked with all the sellers about them, and got the date codes. They appear to be correct for the amp.
So, besides the speakers listed on 'net sites, this speaker appears to have been used for a while. However, be aware the 10J4 comes in varieties. There's at least the 10J4-2 and 10J4-3. I haven't yet learned what the different nomenclature means, but my data show the -2 to be found as original equipment in earlier amps, the -3 in later examples.
If you want original, try the GBase Mall. There's a vendor on there with a wide selection of vintage speakers. I think Gregg Hopkins of Vintage-Amp has a varying selection, also.
There are lots of '62 owners in the group. They should be able to add to this thread if they have an original speaker.
About the 6G2/6G2A? What's the difference? I find the 6G2 nomenclature used in amps made after the middle of '62, both brown and black, the 6G2A before the middle of '62. I haven't found the date of the change yet. The A is always hand written on the tube chart after the printed 6G2.
What resistance considerations are there for the external cabs? I want to pick up a brownie to keep my BFWK company and have a Vibroverb-looking extension cab built.

I don't have your e-mail address either, but here goes. The auction numbers for the three eBay units are 7300518983, 7305809467, and 7303902993. When you do a search, just put any of these numbers in as the search term.

There's also a tremendous site with a breakdown and lots of closeups of a November '61 Princeton. Its URL is http://www.classicamplifiers.com/1961_FenderPrinceton.htm

One of the eBay sellers listed his amp as having a 10J4, but when I asked him about it, he said he just listed it that way because he read on the 'net that it should have that speaker. He knew his wasn't stamped with the 10J4 marking, but instead was stamped 10JB-14.

If you look at the '61, the description of the picture will appear if you hold your mouse pointer over it. It also says it's a 10J4, but you can see clearly that it's also a 10JB-14.

I have a '65 Princeton with a 10J4-3 in it, it doesn't look like these speakers.

The seller of the amp who ended the auction early has talked with me at length about the speaker. He says it's thin-sounding to him. However, he ended the auction because he found the cone was ripped a little, so he may never have heard it when it was good.

The third seller is really no help. If you look at his answers to the questions, you can see that he used a mirror to get the speaker codes, then lists the 10JB-14 as a 41-BJ01!!! This auction is still underway, and he's listed a lot of other information about the amp for your reference.

I notice all the 10JB-14 speakers I've cataloged are manufactured in 1961, even though 3 of the 4 are in amps date coded 1962.

I say they'd be very hard to find. I've been looking for one, and I can't even find a reference to them anywhere on the 'net. That makes it just the kind of oddball I want!

I'm trying to locate Oxford to see if they have a historian who can shed light on this, but they seem to be MIA also. Have they been bought, merged, renamed? Are they now part of the Harmon group of companies? I sent a query to the EIA today, asking what became of them. If somebody else already knows, please post. If not, I'll post if I get a reply from EIA.

Nevada, thanks for the education, by the way mine has a A handwritten. The information you provided is all based on the Oxford, Ampwares says it also came with a Jensen C10R does anyone have an info on whether that is correct?

Nevada, got the email on it this time.

As soon as its CTS AlNiCo gets back from Ted Weber and I get it reassembled, I'll do that.
In the meantime, I got so excited about the Oxford 10JB-14, that I just made an offer to buy the one from the owner who's been talking to me about it for a couple of weeks.
I'll have to send 2 pictures.

Oops. Mea culpa. Pardon my ignorant faux pas. I think what I meant to ask was whether anyone can refer me to a possible source for a jack plate.

Hey C.,

I know who you mean, and I've been looking for him for a while. I think he's gone MIA. I haven't been able to find his site for months.

When I Google him , I get a site that sounds like it's going to be right, then when you open it, it's just a site with a bunch of dating (not Fender amps) type URL links.

Do you have a current address?

Thanks,

Nevada

Who knows how to remove that last pesky retaining nut for the pilot light assembly to free the face plate from the chassis? The assembly blocks access to the nut on the inside of the chassis, and there's no grip on the outside of the face plate, since the jewel screws in there and it seems to have a normal thread, which would turn in the same direction as the retaining nut. Is there a special tool or secret technique?

Thanks

I removed my chassis to take a look, and I've been staring at the pilot light assembly and scratching my head for 15 minutes and haven't really come up with anything other than theoretical, therefore untested, solutions.

a) using a straight screw driver, place it against the nut and whack it with a hammer to try and break the nut loose. I've used this in other situations successfully. But your amp's the Guinea Pig today Nevada!

b) completely untested...find some sort of round medium-hard rubber object, preferably with a conical shape, that you can jam into the opening and maybe turn the housing. You might have to jam a small screwdriver between the nut and the bracket that holds the bulb socket. Again, Nevada, your amp's the Guinea Pig...

Good luck!

C.,
When you feel bad, go play a brown amp, it'll make you feel better.

6,
What a guy. You mean you took your chassis out just to look at that for me? Now that's a brother for you.
I've has those same ideas. I wasn't willing to do the screwdriver whack, and still looking for the right cone thing for that other technique. Even with that idea, it's so cramped there. I've tried to get a spanner wrench in there to hold the nut, not enough room. I've tried to get plastic, non-marking pliers in there, same deal. I begin to think Leo didn't want us to remove those face plates.

If anybody comes up with another idea or tool, please speak up. This is the right forum for speakers, isn't it? If I succeed, I'll let you know how it was done.

Thanks, all.

NV,
Yep, I did remove it just to try and find a solution to your dilemma, but now that I have it sitting on my bench, I think I'll make an overdue upgrade. Yes, I'm going to out out and buy some new filter caps! Time to retire that 41 year old can cap. I've got some gigs, and studio time, coming up and I want my Prince to be in tip-top shape.

Hi All!

I finally put in new filter caps. The original can cap was 3X20uf 450V. I used 3 NTE 22uf 450V axials and mounted them inside the chassis above the can cap punch out . They are resting on a piece of foam.

I had to rebias, with the new caps it was reading around 30ma. I took it down to 21ma.
BTW, when setting the bias on these amps, short out the tremolo, it's actually always on. Even with Intensity at zero, the reading still fluctuates. I used my footswitch, but you can also use a shorted RCA plug. Some 6G2 users have reported a slight volume gain when the tremolo is off, though I didn't hear a difference when I tried that.

The amp seems to have a bit more punch with the new caps, but isn't any quieter than the very old but still functioning 41 year old caps.

hi 6v6man!
i thought it was a great move to open the "club" for the 6G3 as well.
now, seeing that all the other brown-amp users/owners have no real place to go on the fdp - what do you think about changing this place to be the "home of the browns" - or something along that line?
just a thought!
best - C.

Hi Carsten!
How about starting another club? For one or more of the higher powered Brown & White amps; Super, Pro, Twin, Bassman, Bandmaster, Tremolux, Vibrolux, Showman, Concert, and Vibroverb.Or maybe they should be grouped into clubs of similar features or power ratings. I'd be glad to host a photo gallery on my Yahoo page if no one else in the club has that capability.

My main reasons for including 6G2s & 6G3s together is that they both use 6V6s, and both have tremolos that operate by varying the bias on the power tubes.

cheers,
6V6man

Hi, guys would like some input on a new speaker for my 62 Princeton:
Ted @ Weber recommended "The speaker we sell the most of to owners of that amp is the 10F150T, 25 watts, lightly doped.
Big, tight low end, with lots of punch and dynamics" but I would also like to get some input on the Weber 10A150 AlNICo. I have a Jensen reissue c10Q in it now.
