By the time it reaches California I hope it is still a vacuum tube. Hard telling what music Cowen tortured it with. Maybe once it returns to Indiana I can send it on to Ohio.

well I couldn't stand the anxiousness of waiting( for the prize package) so I ordered something (resembling) of what you have going around. Probably not even close...but.. I might get lucky. (this 6as7 thread?) to go with the Cwing of course! or that 5998, or that 6080 GB, or the....

I appreciate your caution. It is certainly possible that it could get lost at my place and never make it to California. lol

I am trying to recall. Would you be listening in a Bottlehead Crack or a Darkvoice or what? If so I might have to build another loaner amp.

I hear you, and I already have something that is very likely as good: A "real" Melz 1578 dated 1958.

But still, I would really like the chance to hear Paladin's 58 Melz.

I have a Glenn OTL, which requires only one SN7 driver.

Got a link? I would be curious what you found.

I kept trying to tell him, but he wouldn't listen.

Oh ok, most of these guys own one of my amps, I can recall someone mentioning a Glenn before.

And I own other 58 Melz including the 1578, these have solid plates and when several have listened they can talk about perceptions. I am up to 14 people who have given detailed responses so I have a fair idea how it is doing.

no thanks...

 

[Paladin79]

no thanks...

I can send you another Marconi if you like.

 

[bcowen]

I can send you another Marconi if you like.

You sent him a Marconi too?

Marconi hoarder....

 

[JKDJedi]

I can send you another Marconi if you like.

I was gonna ask if I should send it to @bcowen but looks like he got the honors already!!

The fact that they have the same date code is quite interesting. "GK" in the Sylvania dating scheme corresponds to October, 1960. I suspect that is likely that these are simply cosmetic changes, but since you have both you can verify.

Yeah thats what the seller touted as well - speculation that production went through some changeover in process manufacturing to explain the difference in bases and micas.

That being said, after listening to an hour of music on each tube, my initial takeaway is that weirdly, the double mica (black bottom base) feels like it has slightly more gain as a result of the lack of the third mica at the top. It is a touch louder (as a results a perceived wider soundstage, more reverb). Everything gets a slight boost, bringing the highs at touch points of fatigue/grate every so often. I didn't experience anything like that with the triple mica (gray bottom)...well controlled, no fatigue. It's almost as if the extra mica regulates that flow just enough. In this, I am running these GB-6080 with a Sylvania 7AF7 for a driver, and my dac is set to NOS mode. It's very interesting indeed. So yeah, both tonally the same. But the double mica is a touch louder/wider enough that it brings touches of the high ranges into the fringe of fatigue.

@bcowen -- Maybe if you mark it 'IMPORTANT -- MAIL-IN ELECTION BALLOT' it'll get here sooner.

On 2nd thought DON'T DO THAT!!!

I only do that with fake tubes.

Well, this is the 6AS7 thread, and not the 6SN7 thread, sorry, but just so folks know these exist, this is a "real" 1578, dated X-58, with perforated plates, tabbed mica spacers and metal springs attached to the top mica. And I have seen one dated 1956. So these older ones are out there.
