I'm sitting in with Matt @ 1400 hours. I prefer evening but it's Halloween. And I don't wanna wait a-n-y longer till another evening fits his schedule, so the afternoon it is! Though, you'd be the exception - between your vinyl collection and his, y'all would be there till midnight. :normal_smile :

Hey guys, I had a question for you all about current production tubes. I'm a bit anal and like the idea of using current production (even though the price is higher) for the comfort of knowing I can always get more later.

Anyway with that out of the way, I'm looking to get a WA5-LE, so what are your guys' picks for 274B, 300B, and 6SN7 current production? I know that for 274B and 300B people seem to like Sophia, EAT, and Psvane/Shuggies. Is there any reason you prefer one over the other? Sound stage differences, price, longevity, anything to differentiate? (I know they don't all make 274B AND 300B, but they seem to be the top contenders...let me know if I'm wrong).

I'm also mostly in the dark regarding 6SN7 current production. The only thing I know of is Shuggies with their CV-181-Z. Is there anything else, or is this the way to go?

Also, where do you guys like to buy your current production?

Thanks so much for putting up with me, I appreciate any answers I get :)

NOS tubes will last very long time, if you don't roll tubes as much you can get two set of the very best tubes and they will last longer than the amp.  Not saying WA5LE will not last you forever.

 

NOS, I personally prefer EML 5U4G and 300B mesh over regular Sophia's offering.  I have not tried the Carbon Princess yet.  It is the sound signature, details, and soundstage, the EML just do everything better.

 

The only current production 6SN7 I tried is the Shuggies CV181Z and I like them but just not as much as NOS' offering.

 

Hope this helps

+1 good current production offerings, but nos is better.

a single pair of metal mullard gz34s will last forever, any nos tube thats strong will last a long time as well. also some current production tubes arent as durable and depending on the amp, can have a shorter lifetime.

Does anyone know how long caps and other amp components last before they need to be replaced. I here that caps will eventually dry up and not sound good anymore.

Good question, I want to know too.  My vintage Marantz receivers from late 70s, early 80s still sound very good.  Better than some new SS amps I tried.

I think all military spec tubes will last forever if properly taken care of.  I think power on, off, on, and off in short period of time will kill any tubes.  I'm religious not to turn off the amp at least it is on for at least an hour.  If I'm only have time for a quick listen, I will just use SS amp.

I had my late 70s Sansui benched. Visually, the Tech reported all of the caps looked very good. And their numbers were very good and well within spec leaning towards new.

Thanks for your advice. Aren't EMLs current production? How do you feel about 5U4G vs. 274B?

Which 6SN7 did you like better than Shuggies?

Thank you!

I have read that stuff like the Sophia dies early, yeah. But I guess the way I see it I prefer to be able to continuously buy stuff instead of worry that supply will dry up.

Do you personally like the Mullard as a rectifier over other offerings, or just commenting on longevity?

my sophia lasted a long time in WA6-SE and never died, i sold it and it should still be going strong. it just depends on the amp, i've heard of EML tubes lasting less than 500 hours (few months), some have used them for years without issues.

 

mullard just commenting on longevity. they [GZ34] last forever, like literally, i think i remember seeing somewhere that they have like 100,000 hour lifetime or something crazy like that.

they do sound good, the metal base does at least. but theres other nice tubes around as well.

Noted thanks. So then what should I look for with NOS if I were to go that route? It just seems risky to me given that supply can and will dry up.

Does NOS generally outperform current production, or is it just preferred because they can be cheap? Perhaps a mix of NOS and current production is optimal?

Early production of Sophia did have issue of longevity, not lasting for more than a year.  Jack did spoke to Sophia and we did get portion credit or they replace it with newer production.  I have my Sophia replaced and the new one lasted me over an year before I sold it. EML are current production and they have been proved to be very good sounding tubes.  EML does have longevity issue too in the early production, they have since changed just like Sophia.  Unlike Sophia, I do not have any issues with both EML 274B and EML 5U4G.

 

5U4G - dynamic, details, and soundstage depth

274B - one word "romantic" 

 

If you are getting tubes for WA5/LE, here are my recommendation.

 

Rectifier - 596 or EML 5U4G

Driver - TS 6SN7 BGRP or Brimar CV 1988

Power - EML 300B

Most NOS are more expensive. They do sound better than most current production.

umm, just a good credible seller and that the tube tests well and appears to be in good shape.

 

and yes, they generally outperform current production, they just don't make them like they used to. they can be cheap to very expensive. i think generally, most NOS, especially the rare varieties, are much better than current production. very few current productions come close, the EML and Sophia are nice and sound as good as a good NOS, but theres some that still sound better. and NOS can be found either much better and more expensive, or similar performance, slightly better for much cheaper.
