I was planning to use   my 6F8G tubes on my Woo amp but looks like i can plug my 6F8G adapter in my 6sn7 adapter with my MK3 that's a nice bonus great. I did not know that .

  Hi!
I've had the LD MKIV SE for about 3 years now but only recently (past 6 months or so) started tube rolling..... [snip]
Just wanted to say thank you to everyone in this thread for all the usefull information! Oh, and I got a pair of 6N5S's on the way too and an external psu

Welcome to the forum! :)
 
It's great to know that you have benefited from our experiences as we have searched and trialed tube after tube in our amazing Little Dots. And when you get your 6N5Ss and psu up and running, I hope you tell us about your experiences as well.
 
Since the 6N5S is in fact different than the 6N13S, which many believe to be a best buy, I am very curious how these two compare. Another tube I am curious about is the Chinese Dawn Sound 6N13P.
 
Soon I expect to obtain an OTL based on a pair of 6AS7 and I can hardly wait to try these myself. :)
 
Cheers!

Welcome to the forum MisterX!,,
 
The way to go for superior bass and overall best performance for the LD is to get the 2.5A power tubes from the 6AS7/6080 families. Congrats on your beautiful work with your mods!

So the 6N13S is believed to be the best buy? Hm, I did not know that. May have to buy some of those to:) These tubes are so cheap anyway, I got the 6N5S pair for $20 + shipping. They're NOS tubes from 1963, hope they're good:) I'll share may experience when I got everything setup for sure.

Yes, that's what I figured. Lets hope the 6N5S's I got on the way are as good as i hope. Funny thing about rolling power tubes in the LD, I think it impacts the sound just as much if not even more than rolling driver tubes.

If anyone was wondering what the difference between the Lorenz C3G and Siemens C3GS looks like, here it is:)

Lorenz on the left and Siemens on the right. Cant say that I noticed a big difference in sound, though the Siemens are a lot quieter than the Lorenz when using my sensitive W1000X cans.

Fascinating! From everything I have read, I was quite sure all C3G were manufactured by Siemens, regardless of the printed brand. And that still may be the case. It is possible that both were manufactured by Siemens, but at different points in time. On the other hand, the differences are quite significant, which does suggest different factories.
 
Since we can't see the guts when we buy these tubes, I wonder if we could surmise that gold pins = Siemens and standard pins = Lorenz or other source?

Some time back when I contacted a prospective seller in Germany he stated that the Lorenz C3g was made in a factory in Berlin by Lorenz. There are Telefunken and Valvo versions of the C3g as well.
 
Somebody in Germany is selling a large lot of 80 used C3g and C3m tubes:
 
C3g Telefunken : 50 Stück/ Pcs
C3g Lorenz : 18 Stück / Pcs
C3g Siemens : 11 Stück / Pcs
C3g Valvo : 2 Stück / Pcs
-------------
C3m Telefunken 3x
C3m Lorenz 3x
C3m Siemens 1x
 
So far the bidding is up to around 27 Euro; shipping is Euro 35 to the US. The auction ends in 23 hours.

It is too much for me to absorb. If somebody decides to buy, please save me two Telefunken tubes!

  Hi!
I've had the LD MKIV SE for about 3 years now but only recently (past 6 months or so) started tube rolling. I've read this thread from the beginning right to the end. It only took me a month or two
biggrin.gif
But it was a good read to say the least! So much information in here it's incredible! As most people (I assume) I read the first post and ordered a matched pair of waay overpriced 6ZH1P-EV. Great tubes overall but nothing compared to the 6HM5's I moved on to later as I kept reading this thread. They really took the LD to a new level.
 
I skipped the breadboard adapters and using double triodes as driver tubes. As I'm into PC modding, naturally I want things to look just as good as it performs. So no flying wires for me, lol. Instead I went straight to the C3G and 6SN7 combo with adapters after reading hypnos1's comments on those tubes. I've only tried 2 sets of powertube replacements yet. First I got the psvane UK-6SN7's. I've never heard such a dramatic change in sound as I did with the psvanes in the LD. Much more clear and detailed sound compared to the stock 6H30PI's. A couple days ago I got a pair of Sylvania 6F8G's with adapters. They are burning in as I type this but first impressions is that they are a tad warmer than the psvane's and not as much bass neither. But that could change as I put more hours on them. Here's some pics of my setup

Psvane UK 6SN7 and Siemens C3GS with chinese adapters that I modified to look a little nicer:) I filed off the socket mounts and painted them matte black.

Here's the 6F8G's. They get quite tall with two adapters:) Just wanted to say thank you to everyone in this thread for all the usefull information! Oh, and I got a pair of 6N5S's on the way too and an external psu

Hi MisterX, and welcome...to the most helpful (IMHO) thread in the entire forum lol! This past year and a half has been the best time I've had in years!!
 
May I say it is MOST refreshing that you have taken the time and trouble to plough through the entire thread...WELL DONE!  I'm sure you have picked up a good few tips over and above the obvious ones - and had a bit of fun also? 
wink.gif
...
 
And well done for choosing what I firmly believe to be one of the (if not THE!) best driver tubes on the planet...and bravo also for freeing them from their prison. If they are NOS you won't believe either just how much better they get up to (and above) 50hrs' burn-in - you're in for some magical listening methinks (no...I KNOW!).
 
And as A11 says, you must try the 6N13S powers...I must admit I was very(pleasantly) surprised at how well they perform in my new Feliks-Audio Elise. You would have to spend a good deal more (on something like the Chatham or Tung Sol/Chatham 6AS7G) to get any better performance, IMHO.
 
You have already taken the humble LD to a level WAY beyond stock....just wait 'til you get those next-step power tubes up and running!

 (they trounce even my nice PsVane CV181TIIs..)
 
Happy rolling!...

Yeah, all Siemens branded ones seems to have gold pins.

Thank you hypnos1! :)
 
Yes, very helpful thread indeed this one:) A lot of late nights reading through it though:)
 
The C3GS's I got are NOS and I'm very happy with them to say the least. Don't really feel the need to roll driver tubes for some time unless I build a nice looking adapter to roll double triodes
L3000.gif

 
So you're also recommending the 6N13S's, damn it, lol. Have you by any chance compared them to the 6N5S's?

Hi again -MX-
 
NOS 'S's?...doubly well done - as the saying goes..."you ain't seen nothin' yet"!!..(50+ hrs, remember?...
biggrin.gif
).
 
I applaud your enthusiasm to build for double triodes, and it would be an interesting exercise...but I fear you would have to spend a great deal of money to get anywhere NEAR the C3GSs...
wink_face.gif
...
 
I must admit to not having tried the 6N5S, so we all look forward to your comparison?!...
 
Cheers...

Hi,
 
Like I said I don't feel the need but IF I were to roll driver tubes it has to be double triodes. Because I'm not going back to EF95 tubes, ever
bigsmile_face.gif
 But first I need to get those 6N5S's up'n runnin. Really looking forward to it:)

Hello LD crew. Thinking about pulling the trigger on a set of hifiman he560 cans, but wondering about compatabity with the LD mk iii. I've currently got some C3G's and 6SN7's in there right now, but being that the 560's are low impedance cans, I know they won't like the 6SN7's. I'd originally purchased and rolled my mk iii because I was thinking of going the Senn HD 800 route, but have since been semi redirected to the hifiman cans. My endgame amp will be a WA22, but I'm a year away from that still. Anyone have any insight into this? Thanks
