Just to echo HA's comment, you absolutely cannot use a 6DJ8 in the DV336SE.
 
You might look for a tall-boy CBS-Hytron 6SN7GT - often very reasonably priced, and very good sounding.

Thanks Skylab.
 
Advice taken (here). A matched set of CBS tube's seems like a simple way to enter the world of tube rolling.
 
Given that most of the 5998's I see online are now in the $100+ range, I just bought the local seller's Tung Sol for $50, and will now start post-diving in a search for a complimentary tube.
 
This should give me two great sets of tube's to play with out of the gate.
 
BTW:  In general terms, with traditional HiFi I've always believed in the Linn System Heirarchy model.  Do the same general rules apply in the headphone world?  That is...is a better (any) outboard DAC for a PC source more impactful to the quality of sound than better tubes in the amplifier, which in turn should be thought of as more impactful than improved headphone cables?

After a minor scare, I've now been happily listening to the Tung Sol 5998 while I wait on the CBS tubes to arrive.  It is several orders of magnitude better than the stock tubes.  Out of the box I was incredibly unhappy with the Darkvoice, and really thought I'd made a mistake.  But the 5998 has addressed nearly all my complaints.  My one remaining concern is that the bottom octave is still pretty lacking.  I know that the K702 is not known for it's bass performance, but I was hoping to get a bit more balance than I have so far.
 
Since I'll still need to replace the front stock tube, does anyone have suggestions for a great tube that compliments the 5998 that might also bring forward some of the bass without overly compromising the rest of the sound?
 
Thanks.

Try the CBS tube first, and then post what you think is lacking or needs to change, and then someone can post, "well such and such a tube will have more of this and less of that, so try X brand model Y"
 
I don't have a 336i anymore, but I posted my favorite tubes on the previous page.  A source upgrade will be helpful once you have the stock tubes replaced.  The 336i didn't come with good tubes.  My WA6 came with much better stock tubes than the 336i, and it still improved with upgrades.

Would a Darkvoice 336SE with Tung Sol 5998 and Sylvania 6SN7GT tubes sound noticeably warmer than a Darkvoice 337 with Tung sol 5998 and JAN Philips 6SJ7WGT driver tubes? Thinking of downgrading but would prefer a slighter warmer sound, as from what I've read the DV337 sounds better than the 336 but I'm hoping not to lose too much of the tubey warmness

 

[Skylab]

In my opinion, the 336 SE would not sound warmer. And the 337 sounds better.

Hi guys, 
 
This is my first time posting here, hope you guys can help me out. I own a Figaro 336 and recently I've bought a RCA 6AS7G and RCA 6SN7GTB off ebay. I've used them on my amp and this is what happens,
 
1) Switched on the amp, and a "pop" sound can be heard on the right channel of my headphone. When I try to play songs, there is no sound on the left channel.
 
2) I've decided to mix in my stock chinese tubes
- RCA 6AS7G +  6sn7 (stock) - no "pop" and sound present in both channels.
- 6as7g (stock) + RCA 6SN7GTB - "pop" present, sound also present in both channels.
 
Did I get a faulty RCA 6SN7GTB? Is the "pop" sound harmful to my headphones, or does using any of the tubes harm my amp? Your help is much appreciated.
 
Many thanks.
Many thanks.

Edit: Hi the weird thing is that it sometimes work with both my RCA tubes and sometimes doesn't (only left side no sound). Strange. Does anyone experienced the same thing as I do?

Finally solved the problem, turns out that the RCA 6SN7GTB tube doesn't sit nicely in the tube socket. I have to tilt the tube to the left, so that the tube pins can fully come in contact with the socket.

hi everyone, just bought the la figaro 336c.  I'm really excited to receive it soon.  So I'm new to this tube rolling thing and I will be spending time to read this thread and the other to figure it out.  This 99 page thing is really daunting haha.  Anyways, are there any MUST get tubes, sorta like the standard typical good upgrade.
 
If this helps, I like listening to electronic music and rock from 5-10 years ago and I will be using a dt880 250 ohm 2005 version.
 
Any recommendations for the price ranges of
 
<30 dollars
30-50 dollars
50-70 dollars
 
for both tubes?
 
THANK YOU EVERYONE!

I would start with a basic tube set to replace the stock tubes that are not all that good.  Get an RCA 6AS7G and a Sylvania 6SN7WGT.  The combo is nice, and should not cost more than $60 total.  You might be best off buying tubes like this in the FS forums here on head-fi.

 

[rontruong]

thanks skylab!
 
I'm looking around the FS for those two tubes, would you recommend any of these other ones that I found on the forum besides the RCA 6AS7G and the Sylvania 6SN7WGT?  If other tubes that might pair good are cheap, I'll try to buy them too... otherwise I'll shoot for those 2 you  recommended
 
also what is a typical price w/o shipping for those each tube?
 
seller 1
Philips JAN 6SJ7WGT
RCA 6AS7G
Philips JAN 6080WC
Tung-Sol 5998.
 
seller 2
Sylvania 6SN7WGT brown base
Sylvania JAN-CHS-6SN7W blk base, green lettering
Sylvania JAN-CHS VT231 bottom getter
Raytheon 6SN7WGT brown base
Raytheon JAN-CRP-GT VT231
Philco 6SN7GT bottom getter
 
 
TY!

I would get the Tung Sol 5998 and the Sylvania Jan-CHS VT231 bottom getter, but that's just me.  It was fantastic on my old 336i with almost everything (IEM, Sennheiser, Denon, Ultrasone, ATH).  It was especially good with my HD600.
 
That combo was slightly aggressive with my Grado RS-1 (but still fairly good with flat pads on the RS-1).  For the RS-1 I used to leave the 5998 in the back and switch the front tube to a Hytron 5692 brown-base.  With a SR-325i I would use the RCA 6AS7G and 5692.  
 
I haven't tried any of the other tubes you mentioned with 336i, but I seem to recall my GE and Raytheon 6080 tubes sounded less warm and more neutral (less tubey), which worked better with my Darth Beyer (for the short time I had either pair).
