Hmm, I emailed them on Jan 15 asking if they had any TS 5598's and was told they had no stock.

But since all 5998's were made by Tung-Sol (I think), they probably have TS made but not TS labelled 5998's.

Well, they told me that's what they are sending me, and I asked specifically, so let's see...I should know in a few days...

O.o, i think it is time to procure a spare/backup 5998

Finally procured an RCA JAN CRC 6AS7, along with a lot of 3 civilian RCA 6AS7G coke bottles and 6 GE 6AS7G regular bottles.

The JAN tube is an oldie, silver print, from the early '50's. I put it in the amplifier last night and it added to the hum from the JAN HYTRON 6SN7 that was already in the front. I left this combo on for a few hours and when I returned the hum was greatly diminished.

I picked up a pair of RCA Smoked/Grey glass VT-231's recently.

Overall a fantastic sounding tube. I had previously written off RCA from some GTB's I had that just didn't do it for me. The smoked glass tubes have significantly better highs and just feel more musical and more balanced than the GTB's I had.

I think this may replace my previous favorite tube which was a brown base Sylvania JAN 6SN7WGTA with black parallel plates with 3 holes similar to what the Bad Boys have. In general I actually prefer the Sylvania as the high's just seem more natural especially with vocals. What I like about the RCA is the lower frequencies are a bit fuller and the slightly rolled off highs are a bit more forgiving than the Sylvania with some tracks. The Sylvania is very revealing which can manifest as fatiguing brightness on some tracks that are poorly recorded/mastered. I'll probably keep the RCA in as my day to day tube, and pop in the Sylvania when I just need to hear well recorded vocals as they should be.

TS5998 in the back for all tests.

P.S. It took about 36 hours to burn the hum out of these tubes.

I'd like to go in on that offer HeadphoneAddict, but I'm moving soon and I need all the cash I can find

6as7g still sounds great, didn't change really that much after time, maybe slightly. Sounded pretty much great right from the start :>.

Sorry for bumping in to this thread, but since you guys are the Darkvoice-tube-rolling-guru's I have a question: for my K701's I sort-of decided to go for the Darkvoice amp. The only question left is which one to choose: DV332 or DV336? From what I read the 332 is more analytical while the 336 has a warmer sound. Would you think that the 336 is the better choice if I want some more and extended bass coming out of the K701's? Or can I tweak the sound on both the 332 and 336 to my liking with tube-rolling?

Thanks!

Ben

I think Darkvoice will release new versions of their amps soon.

Judging from things I've read about the 332 I think you can tweak both pretty much to your liking. I have never heard the 332 though, so not talking out of experience.

I have heard the 332 and 336 and while both of them have the same sonic signature, the 336 is distinctly "lusher", i.e. more "tubish" as compared to the 332 which is cleaner sounding and perhaps a tad more solid-state-esque. I like the 336 because there are tons of 6sn7/6as7 tubes out there to change the sound to your liking. The 332 is perhaps more limited in tube choices, but both of them are nice amps.

I would think that the warm tone of the 336+ the K701s would be a nice match, but YYMV.

Do you mean right out of the box? Or do I need to get some warm tubes as well?

I would replace the stock tubes right away, they are ok, but that is it.

Ben,

I have the 336i and the AKG 701. IMHO, I think the pairing sounds very good. As others have already said, replacing the factory tubes can make a significant improvement (although it's still wonderful right out of the box)... good luck.

I wouldn't want to embarrass myself trying to describe the sound. But what I will say is that there are details in the music I had never heard before now... even the bass has impact, when appropriate. If I had to sum it up in just a few words... it would be: smooth, spacious, and detailed. If you like jazz... wow!
