They look nice, though.

If you want to try the 5692 without reds prices look at the brown base CBS / Hytrons.

LOL! I've never been a fan of the sound of the RCA 5692 either. I agree with Stavros, the CBS brown base 5692 sounds much, much better. I've never been lucky enough to hear the Swedes.

Read somewhere that very early 5692 production were good, but soon  they become average. I tried them ones, got from Stavros, but later, his advise to, bought GE 5692 Brown base and they are very good tubes and do not cost that much.

Anyone know if the Raytheon and Hytron 5692 are the same?

GE 6SN7GT

 

According to the 6SN7 Identification Guide thread, the GE 6SN7GT was manufactured in Canada. However, it would appear that this tube was manufactured in the US. However, I have never seen a tube code resembling "43-L4

 

Otherwise, black T-plates and nearly transparent rectangular micas, top and bottom, seem to fit the description. Does anyone have any knowledge of or experience with this tube?

Oh... I just found this picture and the top mica is somewhat different looking......

I believe they are Raytheons.

The Canada made GE 6SN7WGT brown base are really nice tubes and often bargain priced.

Thanks! After checking some listings on eBay, it certainly does look like an early T-plate Raytheon VT-231, and there seems to be not much love for this tube. However I purchased a lot of 5 tubes, including this GE/Raytheon, and three appear to be pretty good catches - Tung-Sol BG/RP, Sylvania VT-231 and a gray glass National Union, so nothing to complain about. :)

Don't buy too much into what you read before hearing them for yourself.  My favorite 6SN7 is not especially well liked around here.  Really it's good fortune if you take a liking to a tube most people don't care for, because then you don't have to spend as much to buy them.

post #3897 of 4187

Thanks for the advice. I do try to maintain a very open mind as I am running these tubes in a Little Dot 1+, which is a hybrid amp (with a MUSES 02 opamp) designed around a pair of 6AK5 pentodes strapped as triodes. From the experience of a fellow LD1+ owner, I have learned that 6DJ8s sound somewhat different in the LD as compared to the Lyr, and similarly, I am quite sure that 6SN7s in the LD also sound somewhat different compared to a Darkvoice, or what have you. So while I do try to purchase well-regarded tubes when I can find them at a good price, I don't put much stock in claims that any particular tube is the "Holy Grail"... Different ears and different gear....

 

My current reference tube is a Holland-made E80CC. Eventually, I hope to cobble together an adapter to enable me to run a pair of C3gs, but for now, that project is on the back burner, as I am simply having too much fun with the 6SN7s. So far, I am really liking how the early Sylvanias sound in my LD, but there are many others I have yet to try. :)

 

Skylab: Thanks for the tip regarding the Canada-made GE 6SN7WGT brown base. I will keep an eye out for one.

After receiving a matched pair of Sophia Electric 6sn7 class A for use with my Singlepower MPX3, I thought I would say a few words here about them.

 

Now I've had the MPX3 since about 07 and have tried a myriad of different tubes with it, but settled on a Ken-Rad 6SN7GT VT-231 'black top' as driver, and a pair of matched Sylvanias 6SN7GT VT-231 'bad boys' after many years of testing. I thought I had the sound I wanted down pat - until I received the Sophias.

 

These (the Sophias) are by far the most detailled sounding 6SN7 tubes I've yet to hear. Soundstage is much airier than the Sylvanias to my surprise, instrument separation is absolutely fantastic, they are very neutral tubes compared to most I've tried. I'm still in the process of burning them in, but so far bass is tight and controlled, mids have excellent impact and the treble has great definition. I've tried switching back and forth with the Sylvanias, but I don't think I'll be going back to them. The Sophias are truly excellent in all aspects. I still use the Ken-Rad as driver.

+1. This mirrors my experience with the Sophia's on the Woo WA6 (in comparison to TS 6SN7, haven't tried the Sylvanias).

Yes I also have a pair of matched TS 'mouse ears" 6SN7, Hytrons, RCAs, other Sylvanias (non VT-231), Electro Harmonix, etc... so far the Sophias are a big step up. I'm very happy with them, they were well worth the money.
