6SN7 Tube Addicts - Page 77

post #1141 of 4150

Zaerix definitely made NO tubes.  100% rebrander.  Some of their tubes were made by Mullard and other UK makers, and were very nice.  Some were Russian.  Some were Japanese.  It's always a crap-shoot.  David, those ones in that auction you liked to are the exact same tube as the "Ultron" branded 6SL7GT's I sent you (which are also Russian).  Check it out biggrin.gif

 

I agree with Stavros.  The Russian 1578 never impressed me.  I think it's way overpriced.  I still have one left that I should really sell.

I spent some more time with the new Sovteks -- they are nice and mellow which worked nicely with old jazz recordings but they are too mellow for, say, rock.

I read somewhere that Fivre and RCA had a relationship with respect to tube manufacturing and maybe design.  Does that mean that the Fivres are similar to some of the RCA production?

I agree that the 1578 tube may not be for everyone.

However in my WA5 driving WE300B they outperform the Tung Sol BGRP in terms of resolution and overall drive.

I could see that if the other tubes used with it are on the dry analytical side that the 1578 would not be a good match.

Actually I would say the ATES are closer to RCA, I have some which state under license from RCA.

 

There are so many variants you'll be surprised.

And they do sound so different, some combining the wonderful British sound with some extra qualities.

 

Your Quad are 6SL7, if you look at the labels and tell me what they look like I might be able to help a bit more.

I have used them with various releases of GEC, MWT and Osram 6AS7G as well as various 300B's and PX4's, which I don't think are dry or analytical and still don't like them in my systems I am afraid.

On the other hand Kiertijai reported Craig Uthus thougt they were nice. And so do many others.

Sound preferences are so personal and varied.

My comments apply to my systems and ears only.

I am not a fan of these Russians either, they have a very good low end, but the rest isn't that interesting, but most important, the total picture, which I found not musical enough to get them on my list. Becides, they are very expensive, imo.

Not to mention finding a "real" 1578 is not easy.

More often than not the majority I see listed are just standard metal base 6H8C with a fake stamp.

Those are vastly inferior and really shouldn't be compared.

But yes, it is all about system synergy and personal preference.

How many hours 5692 needs to settle?

I would say 200 hrs as a start for the 5692.

 

Here is an interesting Cossor tube:

 

COSSOR 6SN7GT VALVE L10-N 4J7-1.tiff

That one is rather striking with the gold print right on the glass.  Possibly made by Brimar?

Can someone tell me who makes these tubes?

Came with the Wheatfield Audio HA-2. Most warm and luscious sound.  Anybody knows about this tube?
