For 6AS7G tube rollers here ..... - Page 54

post #796 of 1562

Those differences are exactly what I'm interested in discussing hifiman - and, to be accurate, if you re-read what I quoted and responded to above, DG is talking about how her 600 ohm beyerdynamic T1's sound with the gec tube.    

 

In comparison to hd800's, many beyers have pretty flat impedance curves.  If the T1 is in the same camp (headroom hasn't posted an impedance curve for them for whatever reason), they may well not get the bass boost from a higher impedance cathode follower as opposed to a 5998.  For purposes of illustration, compare the hd800 and dt880 impedance curves:

 

The fact that the 5998 is bassier in DG's setup, and the GEC is bassier in mine, is probably of high relevance to others who may be trying to figure out which, if either of these tubes, is worth buying given their tastes and gear.

My apologies..as i was talking with her concerning the he500..so two stories got a bit mixed up..
I myself never heard a gec..i have bendix and rca and the tungsols.. And the tungsols give me a feeling my he500 gets more power..and not only in the bass..it sounds like the sound is more fuller..like the difference between a copper and silver cable... But as i said before..not every amp reacts same way on different tubes..maybe it has to do with how the amp is built?

Pity i will never ever hear the difference of the best tubes (imho) available anymore as i will be jumping on another wagon in two months time..it was fun...

They are both very similar, and I believe both made by TS. The low impedance gives my HD558s nice drive. The TS WB takes a long time to warm up (20 minutes). During the warmup time you can hear the carbon plates expanding/creaking. I've tried to A/B them and I'm not sure I can tell them apart other than warmup behavior. If I take my placebo, I think I can sense the TS has a wider soundstage, much like is reported for the Bendix 6080...but it's so subtle I'm not sure. I believe they will run a little cold in an unmodified Woo, much like the 5998. I've got a pair of constant current source (variant of the bottlehead speedball) installed in mine to hold the tube at 39ma each side.

It's good. It's my all time fav 6AS7G. Just bought some more actually, get them while they're available but don't overpay them

lol, I got my pair for $10 shipped. biggrin.gif loose glue in the base but doesn't effect the sound whatsoever

I saw that auction too. He always has nice tubes but his prices are all over the place, way over the top
post #807 of 1562

Can anyone identify this tube? Looks like a GE, but there's no "USA" engraved on it.

 

post #808 of 1562

If it has dots printed on the glass it most likely a GE tube

post #809 of 1562
Yup, that's GE for certain.

Hello everyone,

 

I have a 339 amp running 5998 and 5693.  I am wanting a little more punch in the bass  and I am curious about these bad boys http://www.ebay.com/itm/One-Matched-Pair-of-New-Heavy-Duty-Graphite-Plate-6082WB-Tubes-By-Bendix-/370778444872?pt=Vintage_Electronics_R2&hash=item56541e1448.  

 

Are these the rare graphite column 6080wb which are suppose to be better than the 5998?
