Been burning in my Tung Sol 6SN7 for around 95 hours now. Still a hum from the left channel. Is this normal and should I just keep going or did I get a dud?
coolcrew23:
Is that a NOS USA Tung-Sol or the newer Russian issue? Using the Russian 6SN7 you will get a loud hum/buzz in left channel of the Darkvoice. I didn't burn them in because there are so many NOS Tubes that are dead quiet.
It’s the russia one.
So I guess this isn’t isolated. I have another one coming in. Hopefully it’s the USA one or makes no noise. My VSI 6SN7 and RCA 6AS7 was dead quiet.
Ok, good thing I asked thenNo. The 6336 will fry your amp.
I'm afraid they're somewhat rare and expensive. I see for example this on ebay: http://www.ebay.com/itm/One-5998-tube-by-TUNG-SOL-tested-strong-/132361197148.Ok, good thing I asked then
Do tou have any suggestion (maybe a link) to a Tungsol 5998?
Have not been able to find any for sale...
Thanks for your helpI'm afraid they're somewhat rare and expensive. I see for example this on ebay: http://www.ebay.com/itm/One-5998-tube-by-TUNG-SOL-tested-strong-/132361197148.

Does anyone know what are the maximum safe current draw of tubes, both in the power and driver sockets, for DV?
You can see my DV workhorse sitting on top of my AC line conditioners. Monster Power HTPS 7000 and Monster Power AVS 2000 because I was suffering from some AC noise coming in to my power into the building . I had a little noise coming from the drivers of some of the florescence lights and LED's I change those to a different brand with better filtering in him and in some rooms I put back old incontestant lightbulbs, and that took care of the rest of the noise. As for noise floor now you would think you were listening to a $2500 tube amp. Sitting next to it you could see my IFI micro Black Label DAC amp. I have the DAC use as a preamp into the darkVoice that really cleans up and add clarity to your source . At the same time I have my HD 650s plugged into the IFI AMP. Two people can listen at the same time with the set up or I could play around between tube in digital simultaneously listening to both sources . I have nearly 100 tubes for DarkVoice and only one hums. If you're having such problems with all your tubes humming maybe you better start looking elsewhere for the source of the noise. When you start building tube AMPs for yourself your wallet starts hurting.
