Darkvoice 336 + 336i Tuberolling [ tubes ]

Are the RCA gray plates better than the RCA black plates?

The black plates are sure more expensive.. just wondering, because I received two (1 NOS) grey plates from tubeworld when I bought my 336i.

I personally preferred the RCA over the Svetlana. But that's JMO, YMMV.

What does YMMV stand for? I see it pretty frequently, however I've yet to crack the code..

But.. how is that abbreviation correlate with that statement?


"Just my opinion, 'your mileage may vary' "


Sorry for being so hard headed, but I sometimes don't understand these "easy" things.. *smacks head*

"Your Mileage May Vary" is the legal disclaimer in car ads about what your actual gas mileage may be. It's become internet-speak for "your experience may be different from mine".

LMAO ROFL.. sometimes, I am a complete idiot. Or maybe it's the medication I was just recently prescribed.. let's blame it on the medication..

However, I can see the trend starting; just look at the post at the top of this page..

The RCA 6AS7G gray plate sounds expansive and smooth, whereas the black plate is a bit tighter sounding and (IMHO) can even be slightly hard or harsh. Between the two, I more frequently choose the gray plate version. Reportedly, the RCA 6AS7G gray plate coupled with the Tung-Sol 6SN7GT round plate leaves little to be desired. : )

PSS. Could the final ending price break $1,001? ($1,001 sounds better than $1,000) Some of those tubes are MIGHTY expensive..

Hi all

I know this question has been answered umpteen times, but I just want to know if, given my setup (DV336i + low imp MS2 + Tung Sol 6SN7GTB + stock Chinese back tube), will longer burn-in get rid of the hum sound? I read somewhere in this thread that hum sound may not go off in the case of low impedience headphones. Someone also mentioned before that a matching pair of tube can also solve the problem. In that case, will the RCA 6AS7G or Svetlana 6H13C help in this aspect? I'm ready to get a 6AS7 tube but want to make sure that this can also help get rid of the hum, in addition to improving the sonic quality of the 336i.

Without doing the Fitz hum mod (as I'm not technically inclined), how can I eliminate the hum?

Can anyone advise?
Thanks.

This has happened to me, and the hum or noise went away after so many hours. The tube I was using was a RCA 6SN7GT smoked glass..

Another thing that helped, I am not sure of this totally, but by switching out the power cord, instantly, the hum or "noise" became less apparent and wasn't as bothering as before. I don't know if this can be a true factor, but I would like to throw this out as well.

I would give it at least another 24 hours total of burn-in and see if that doesn't help. Either you can leave it on for a few hours a day, or you can listen to music and hope it goes away. For me, this "noise" was to harsh for me to listen to music, so I just let the tube burn-in with some pink noise a few hours a day.





This is as far as I can comment, because I lack the experience, and knowledge others around here have, and will leave it up to them to finish off your question. I am merely sharing my experience when I had tube "hum".

Some tubes are going to hum and not stop. But mostly if they run in for 24 hours they will quiet down. My DV336i does have the Fitz hum mod, however.
