TungSol 6SN7 Mouse Ears + RCA 6AS7G

That's really cool. I've always wanted to try a tung-sol but have always been too worried about the hum.

Only the new re-issue TungSol made in Russia is known to have a significant hum that can be removed after a long period of burn in.
 
I believe @Verhulk, can chime in here as he has that tube and can confirm this.
 
The other TungSols that I do have, if they hum, its not very loudly. I will swap in the mouse ears tomorrow and confirm this as well, but TungSol (as long as it was made in the US) will more than likely not hum for you and if it does, a bit of burn it never hurt anyone

Good to know, thanks. Anything locally I've found have been the Russian ones, but I'll keep an eye out.

Ebay is your friend mate.

And also of course before you buy any tubes, read through the 6SN7 Reference thread.

Also, thanks to @DoctaCosmos, I ordered the ZMF Eikon + Atticus. I was on the fence, but I found the ZMF thread and I just **** it. I was gonna snag the Oris, but I need something that pairs with the DV and at 300ohms, these will do just fine. I also couldn't let the 10% sale go for purchasing both, so I get a pair and probably my gf does as well lol.

Yeah I think I've read that whole thread back and forth a few times hehe. I bought my Sylvania from referencing that thread. Love them. 
A bit reluctant to get tubes shipped over from the US to AUS.

 

[41Venom14]

Haha, oh yeah I totally understand that. Keep us updated if you happen to grab any tubes. Kenrad VT-231 is one of my favorite tubes at the moment. The reference thread said they had the best bass, I doubted them, I was wrong, poor me lol.

I would love a Ken as well - a bit out of my price range just now.

Just wondering, can I use dark voice 336se as a pre-amp into http://www.kingsaudio.com.hk/m03.html?
 
I am not very familiar with the setup but I am guessing laptop(max)->dac (max)->pre amp (max)-> amp (volume control)
 
or should I control the volume at pre amp level?
 
thanks in advance.

You can. Nothing to stop you. I've used DV as preamp into Elise and vice-versa. Volume is controlled at the amp.

did you max your DV?
 
I don't know much about circuits (volt, amp, impedance and etc) so I hope not to blow anything up.

Nope. Here's the funny part. Initially I could increase volume by adjusting both DV and Elise volume knob. A few hours into usage, DV's volume knob becomes redundant. Only the amp's volume knob is in control.
 
You won't blow anything by using DV as a preamp. It's designed with preamp out and will function as a preamp. Same goes for Elise.

About USA made Tung-Sol and hum. Just received a TS 6SN7GTB, left channel hum is unbearable the worst I heard. Skeptical any amount of burn in will tame it down it is so bad but will try.
 
Another fail, someone just sold me bad RCA 6AS7G or so it seems, have no power to drive my 32Ohm cans, distortion at any but the lowest level, badly unbalanced between channels, lotsa blue glow, blue not purple at least, suspect that burning them in isn't going to help. Sigh.

Can you post a pic of the blue valve?

 

[gvl2016]

Here you go. Would be very cool if it also worked.
