The Reference 6SN7 Thread

Not sure if that is it. Haven't seen pics yet. He sells on Audiogon. Price could be less too. Certainly a lot less than the Tung-Sol roundplates.

Well, if they were THAT good, or better, don't you think there would be more discussion on these tubes? I mean it seems every tube has been tried.. except these.

NO. Those tubes are a FLAT RIP-OFF. Just a basic Russian 6N8S with a metal base. No better than the black-base ones you can get for $1 each.

The *actual* 1578 has a totally different plate structure - see here:

RARE! 1 USSR TUBE 1578=6SN7 Unique military development - eBay (item 260261138109 end time Jul-19-08 21:00:00 PDT)

That one IS a 1578. Interesting tube. Some people think it's the best sounding 6SN7 there is - others (including me) were less than impressed. Personally - I wouldn't spend the jack for one. RCA, Ken-Rad, or Sylvania VT-231's all beat the pants off the 1578 IMHO.

Gotcha.

That was the first thing that came up, so I linked it..

Thanks for the info. One guy in that thread liked them a lot. My seller did say they are microphonic, but i don't think that's a problem for me. Anyway, i have a total warranty with him, can return anything, so it's not that risky.

I am interested in hearing from those who have heard these tubes.

Thanks Skylab. I do like the Ken-Rads and Sylvanias a lot. That is what i currently use in both my amps. My seller has the real 1578s you mention. I may just try them out to see for myself in my amps.

If you do, and don't like them, shoot me a PM so I can try one. I wouldn't pay full value, but I'd like to try one nonetheless.

I do suggest trying them out. I found them to be a little grainy and dry sounding, but that is just in my amps. Might be great in other amps, and to other ears

blubliss,

I couldn't resist, but to compliment you on your stunning headphone collection. I'm just speechless...

[blubliss]

Skylab,

Were you able to just drop those ECC32s into your Extreme? Where did you get them, if you don't mind me asking?

My tube seller is a guy on Audiogon, username paul_lindemann. Very nice guy. I've gotten Sylvania VT 231, and WE 2C51 from him for less than others sell them for.

You can send one of them to me, if you'd like.

Yes, the ECC32 works great in the SP Extreme, with no problems. Mikhail from Singlepower even strongly recommended it to me as an excellent driver tube in the Extreme, and indeed it is. I also use one as the driver tube in my SP MPX3. They just sound great. I got them from Brendan at tubeworld.com - brown base NOS Mullards, $200 plus shipping. Expensive, yes, but really great in SP amps. Never tried one in any other amp I have because I am unsure if they would work.

I too have bought tubes from Paul, and he's a great seller.

I did and indeed they are really good! I don't like the russian 1578 as driver tube but 2 of them as powertubes are really nice! That is what most people do, use a different driver and 2 as powertubes, really nice combo.

I have probably 2 up for sale, new....just pm me.

Also 2 sylvania w , wich are extremely rare and highly sought after!

I stick with my just as rare jan philips wgta's.

1 jan philips wgta was better as driver tube then the russian 1578.

But, the russians are up with all the other exotic 6sn7's, that is if you got the real deal!

Lots of other russians are indeed crap, only the real 1578 is a really good tube! hence getting really rare and expensive!
