Yep, they'd be the ones!

Interesting, I've read some pretty bad reviews on the Russian Tung-sol's. At least compared to the old stock American ones. I'd be well up for trying them though if they're good as it's cheap and brand new!

I see MelonHead has one. What's your opinion on the Russian Tung-sol MelonHead?

@Gallic Dweller Thanks, The solderenling tools are in my drawer already. I just want to make some evaluations before doing the Fitz mod.

@Jamie G Unfortunately I don't have deep enough knowledge to make a valid comparison, as I'm a fresh owner of the Darkvoice 336SE, and quality NOS tubes are out of my current budget. After the hum was gone, I was very satisfied with the production of the Russian Tung-sol. A bit dry, but pretty capable in the base and highs. Considering it's price, I will recommend it.

Today I tried the DV 336SE, as a tube preamp in my Electrocompaniet-Proac system. I'm totally amazed how well this small Chinese gem works together with the Audio-gd R2R 11 DAC in a so much bigger chain with the Sylvania 6080 and Shuguang Black Treasure tubes. I reason about buying a second unit which will be part of this living-room set-up.

@MelonHead - Mate, I thought I was delusional in wanting to grab another DV, she's a beauty though, all my headphones want a piece of that Darkvoice sauce!

I'm the first to admit my soldering skills is noob level status, I DO NOT want to screw up this beauty! I'm more than satisfied with the RCA/Tung Sol combo!

Do 6as7 need burning in too?
My RCA 6as7 has hum on right channel :\

@tamio - Indeed, same issue with my RCA, a good 10-15 hours of usage fixed it right up. I had it in the left channel. Now, the hum has gone and sounds wonderful!

Just ordered the TungSol 6SN7GTB and GE 6AS7GA combo to go with the 336SE I just picked up from Massdrop. I had the original 336 and had very fond memories of it back in 2006. Excited to be exploring this hobby again Cheers!

I've settle down now with the Tung Sol 6sn7 & RCA 6AS7g combo, have been very satisfied with this combo without wanting to roll in anything else.

@aznsensazian - She's a good amp my friend, hope it all works out for you!

 

[aznsensazian]

@volly - I am finding that the hd-6xx/hd-650 are magical with this amp. Just so freaking musical

 

[volly]

The Sennies will come out more on the DV, that is for sure! I've been fortunate enough to get my hands on a Schiit Jotunheim, balanced out with the 600/650's is interesting!

I just recently went back to my HD 700's. I forgot how good they are. I am also using JRiver w/ Sonarworks Plug-in for the HD 700 24/96 DLNA to my Marantz NA 7004 > Musical Fidelity M1Dac > Darkvoice.

 

[aznsensazian]

looks good @dobigstuff. How are the hd700s? what is your favorite tube combo with the hd700? I am really enjoying the GE JAN 6SN7WGTA and GE JAN 6AS7GA together. Lots of bass presence and great dynamics for the music I'm listening to currently which happens to be dubstep, lol

I am listening to a DV 336SE as a preamp at this moment, I like it as a preamp better than other preamps in my possession.

My experiences told me that the hum issue of 336SE is related more to the driver tube, less to power tube. I had a quite few driver tubes that hummed, but settled to be OK after burning. I had a couple power tubes that had hums/pops, the burning did not help help at all. I ended up throwing them away except for the most recent one which is still on my tale.

aznsensazian:
My favorite combo is:
USA NOS Tung-Sol 6SN7 GTB Tall Bottle Driver Tube and NOS Western Electric 421 A Power Tube

 

[dobigstuff]

This is another great combo: NOS Jan Sylvania 5998A Power Tube with a NOS Sylvania 6SN7 GTB Driver Tube
