I've bought a pair of RCA 6AS7G (labelled RCA on the photos etc), arrives as 'haltron' brand, not what was in the picture. Rebranded russian 6AS7G, I bought it for 3 times what I would normally pay for that tube.

As the tubes you received were not what was advertised, you're entitled to a full refund. Ebay makes this easy. Just fill out a simple form, they give you a shipping label, and then you get your refund.

What's wrong with Ebay? Ginormous selection, as close to a perfect market as we get (in an academic sense) - an opportunity to play very little for high-quality tubes. Where is the problem?

I got two bad tubes once. The seller was unresponsive. Ebay was. The money was back in my account as soon as the return delivery reached its target, postage paid by Ebay.

No doubt. Some very good sellers on eBay. However I also think there is a lot of sellers selling doggy stuff. I've come across a few Cowboys. I also get the impression there is a few sellers that have bought bad tubes and they flick them off to someone else. Especially if they are rare and expensive. I have learned to spot those auctions. Also hard to get good service overseas. Often the freight back to the seller costs more than the tubes. I would rather buy from a seller who has a massive stock of a particular tube. If you buy a small test sample at it works out then you can stock up. Very unlikely to get problems.

GE6AS7G is a very nice tube. As previously posted it is very close to the Mullard 6080. I'm listening to it right now. The last few days I've just felt it was missing something that the Mullard does well. I've just clicked. It is not as dynamic. A little flatter for a lack of a better word.

Given its sell price it is a great budget tube. It is quiet in my amp where the Mullard is noisy. So I think I will make it my tube of choice. I will evaluate for a little longer first.

^ are you talking about the GE 6AS7GA? If it is, I don't like the bloominess in the bass compared to other tubes.

Most of us have made that mistake. Part of the learning curve. :rolleyes:

Yes I am. Ha. I didn't notice that until you mentioned it. Probably why I thought it was flatter. I hope it doesn't annoy me. I want to like this tube. Not many options for quiet tubes in the Woo WA22.

Sennheiser 650 already has rolled off treble and bloomy bass, switching to a grado headphone as I did now is a lot nicer.

I actually like a semi dark sound signature. Hence I use the classic LCD3. I plan to get the Ether or the HD800 (modified to take some treble of it). So a bit of bloomy bass would be okay.

Still enjoying the tube.

I don't mind the dark signature either, just that 650 + GE 6AS7GA was too much.

At the end of the day I'm enjoying the GE too.

I think you may be right. It may be too dark for the LCD-3 as well. I won't pull it out yet. I will give it time. The set I have in at the moment are also under 10 hours use. So no burn in yet.

One tube I really do like is the Chatham / Tung-Sol 6AS7G. Not the RCA version with the flap down the bottom. The Tung-Sol 6AS7G is a little lean but very lively. A very nice full sound. It suits the LCD-3. I have 3 sets of them and would like more. Very rarely do they come up for sale. However owning 3 sets that should mean they will last 15 years. I should be able to get more in that time.

Anyone knows what kind of tubes are these? except the marking 6080WA on the one on the right there's nothing else, not on the base, not on the glass.. also the one on the left has copper rods and a weird wire with a little spring attached above the base

Badas · Jun 29, 2015 at 5:07 PM

The one on the left looks like an early Sylvania before they went to a 3 micra system. The micras look Sylvania. Support rods don't tho.

The one on the right looks RCA. However the bottle shape at the bottom looks different. It could be Raytheon.

My thoughts there are a lot of honest dealers on ebay no doubt but their are also a lot of nefarious ones which has been my luck lately..

On E-Pay you are better off buying singles and put them together for allot less money then a so called matched pair. Anybody can put two tubes of the
same brand and look similar and call them a matched pair and sell them for 10X the price. I can still buy 6F8 singles for $4 and people are paying $100+
for a matched pair on E-Pay. You just have to know what you are buying there can be NU round plate 6F8s that are labeled GE that cat be gotten for
little.

abvolt · Jun 29, 2015 at 8:05 PM

cool thanks glenn does it matter if their different brands ?

Good point. Good strategy.

In regards to NU. Be aware I have a RCA with NU plates. Very slight internal construction (plates are closer together). The RCA sounds very different.

abvolt said:

Nope. Just get use to the internal design. I have seen the NU 6F8G with about 4 different brands stamped. They are all the same internally.

On the 6AS7G. I have the RCA version myself stamped RCA, Sylvania, Raytheon and Tung-Sol. All are internally the same. All sound the same.

On the Sylvania 6080. I have Sylvania, Brimar and Telefunkin. Once again they are all the same. Don't get fooled to pay Telefunkin prices for a Sylvania.
