I notice that there are some  sellers who know the 'pain price' for some of their stuff.  They price the tubes at a point where you just can't justify buying them.  There are also the truly silly high price, obviously ridiculous, that makes you ask, ala John McEnroe,  "you cant be serious" !

I can only speak for myself but when you see the same high priced tubes being offered over and over you would think that the seller will cut the price.  Sometimes they just don't.  Are they using the old sales technique that car dealers use like putting the convertible sports car in the showroom to just get people looking?

I took a chance as it was advertised as untested and that is probably why I got it at the low price. Gauging it against the sound of the Mullard it is a little woolly in the lows and not as clear or engaging, but that was how the Mullard sounded with little hours on it. For that reason I have a good feeling about how the GEC will blossom with further hours. It certainly doesn't sound like I have bought a plum.

I have seen a dealer selling these for £75 on ebay and in my eyes that is greedy.

The set of CV2984 with a GZ32 and pair of Sylvania VT-231 have my WA22 sounding rather good. Living vicariously is a daily thing on this site.
If there is enough stock and no need to rush for a second pair of the mullard 6080's, don't.

I recently bought a pair of mullards and Bendix 6080wb slotted graphite tubes and the Bendix are fantastic.

More punchy/gutsy than the mullards. Both are warm, the mullards are easy listening and draw me in in a more subtle manner.

I find when the mullards are in I'm happy to keep listening and enjoy with no need to switch off my amp and wait 15 minutes before changing tubes. But I'm usually more drawn to popping in the Bendix tubes in first when wanting something warm.

I had a bit of a deep purple session last week on these.

(A number of other head-fires here rate the Bendix tubes above the mullards)

The Bendix tubes are harder to find (on eBay) but I didn't pay too much more than the mullards at the end - certainly not as much as the tung sol 5998 or my beloved gec6as7g's
post #3303 of 3593

I'd agree with that evaluation, However I'm very fond of my mullards also but my ts 5998's are absolutely superior sounding in every way so much so I had to get a second pair, never had the pleasure of listening to the gec 6as7g's sure would like to though..

Ive rolled GE 6AS7GA on WA2. Its been only couple hours and i'm not hearing anything special.
How long, before they open up?
post #3305 of 3593

not too likely that's a very average sounding tube to began with imo..

Just as jbvolt said the GE is not a great tube.  It is not very detailed and has a top end which is drowned out by the overly boosted mid bass.  Some people like it for those qualities , 'warm or rich' but  without being resolving spatial and 3D or holographic .

You are prolly as open as they get with 48 hrs

all this is  my personal opinion YMMV.

post #3307 of 3593
I've gotta agree with this. Rolled in the GE after using my chatham 6as7g for a couple weeks and wasn't too impress. Bass was a little improved but highs sounded rolled off. Definitely not as spatial or 3D as the 6as7g either...
post #3308 of 3593
The only thing that was "special" about the GE 6AS7GA was that it *was* available true guaranteed NOS from parts express. However, they're out now. So yeah, it's not a tube to search out.

My best guess. N = December, 0 = 1950 and R = factory.

GE 6AS7GAs gave me exactly the same impression in my modified LDIII, (used as a preamp): very good bass, extended highs, a competent tube, but lacking air and space, a "closed in" , centered sound, and some people like it, I respect that, maybe fine for some headphones, or other amps, but in my setup this one is miles away from the great sounding tubes. And one of the best is the GE 6AS7G (without the "A") a "coke bottle" tube. The experts say that GE never manufactured this tube, but rebranded Chatham tubes made in the NJ factory. No surprise from GE giant, it was cheaper to rebrand than to set up a whole new line to build this type of tube. But, most interesting, the GE/Chatham 6AS7G "batch" is almost identical, but not exactly the same as the regular Chathams produced in the same era, and I mean around 1953 to 1959. A few days ago, I finally could get a pair of "NOS spec" Chathams, after some faulty ones, and compare them to my "NOS" GEs. No doubt the Chathams are reference tubes, great body and substance, air and space all around, that special "magic" that even the Mullards 6080 can not quite equal. The GEs do the same in a different way, very similar to the Chathams and a bit lighter sounding, maybe, but with a seductive, airy, 3D sound after proper burn in that is second to none, in my experience. Replacing the Mullards with the GEs was a clear step ahead in sound quality...

When things work out really good it is usually an instance of system synergy to my mind.  Some tubes do a better job at making  that synergy  possible than others.  I can assure you unfortunately, that using the same tubes, doesn't always result in that same magic.

I do think that in a reasonable percentage of situations, that using a suggested tube, can be very helpful at creating the sound you want.  Just don't be surprised if it doesn't.
