I haven't roll in c3g with Cetron 6336b for a long time now. Probably a month. I think I have to do that now at the expense of making the sockets more loose. However one of the 2 guys coming on Monday to my place for the mini meet is an expert solderer. So I will get him to replace my sockets at some point in time.

Alright let me show you how Super 9 looks like with c3g and Cetron 6336b. First of all, this is totally silent. It passed UT's silence test 100%. Secondly, c3g just sound so special in Beautiful Beagle when it's quiet. As Hans said, the bass is 'unprintable' unreal and the clarity, you will see through the smog. If you are taking a walk at dead of night, you want the c3g with you. Look I'm a details guy. I love details and c3g is the master of them all in details.

I'm listening to Sade btw. Good bass !!!

@Althalus the above is the reason you want c3g sockets. The thing with c3g in Glenn's OTL amp is it's not fatiguing despite being very clear. I'm using LCD-2f now and the c3g illuminates it. This is very enjoyable.

I already did include the c3g sockets in my order. Just to make the amp as versatile as possible.

I have just one question.
I went for the otl with 6 output sockets. What are the tubes I can use here without using an adapter. People mention so many tubes in this forum that I loose track about when an adapter is needed for the output tubes and when not.
I know that the question sounds stupid but better asked than buying some tubes and when the amp arrives finding out they won't fit or worse, they do fit but the pin lay-out of the tube is different..... That would be really stupid. Not asking.

The C3g driver tubes seem to make all power tubes sound good.
They seem to make all around them better

Drivers and power tubes in GOTL

Alright @Althalus I'll explain one more time for you or for anyone who needs to know. If you forget, just search for those words in bold in this thread or you are going to remember post #20903.

For illustration I'll post this picture again. For those OTL with tube rectification, there will be another socket to the front left.

Looking from the front of the amp to the back...
. 1st socket - this is for 6sn7 / 12sn7 / 25sn7
. 2nd & 3rd sockets - strictly for c3g (have to use in pairs)
. 4th & 5th sockets - 1st pair of power tubes
. 6th & 7th sockets - 2nd pair of power tubes
. 8th & 9th sockets - 3rd pair of power tubes



Now what to use in those sockets:-
( None of these need any adapters but you can optionally use socket savers to preserve the sockets )

1st socket:- 6sn7 / 12sn7 / 25sn7

. 6sn7 - 6sn7gt, 6sn7gta, 6sn7gtb ( set switch to 6.3 volts)

. 12sn7 - 12sn7gt, 12SL7gt, B36 (set switch to 12.6 volts)

. 25sn7 - 13D1, 1633 (set switch to 25.2 volts)

2nd & 3rd sockets - c3g (any brand)

4th to 9th sockets are strictly for power tubes. So what power tubes can you use?
(one of the combinations below)

. 6 x 6BX7gt or 6BL7gt / gta (use either 6BX7 or 6BL7 any brand - don't mix the type but you can mix brands - these go in 4th to 9th sockets)

. 2 x 6336, 6336a, 6336b (brands can be Tung Sol, Chatham, RCA, Raytheon or Cetron - can ONLY use one pair of these tubes - they can go into either 4th & 5th sockets or 6th & 7th sockets or 8th & 9th sockets)

. 2 x 6as7 or 6080 (they can go into either 4th & 5th sockets or 6th & 7th sockets or 8th & 9th sockets)

. 4 x 6as7 or 6080 (these go into either 1st, 2nd or 3rd power tube slots)

. 2 x Tung Sol 5998 or 7236 (same as per 2 x 6as7 or 6080)

. 4 x Tung Sol 5998 or 7236 (same as per 4 x 6as7 or 6080)

*NOTE:- All these are for the most common type of tubes used in GOTL. Ones that are special and that needs adapters will be addressed separately.

Glad you like them. Of course, the OTL is a very different amp, but with the Cossor 53KU and Tung-Sol 6BX7, these old, embossed Telefunkens are pretty special.

Still looking for the embossed

Ever since I watch Michael Fremer's video of the CD vs Vinyl, I've become more engaged...... not with CD or Vinyl...... but the music he chose to play in it. It's the album 'Avalon' by Roxy Music. Love it and I only got to know Brian Ferry since then. Ok this is the 80s but it's good music. Good lyrics, good voice and..... in the video below I actually notice the female backup singer more.

 

[UntilThen]

In this rendition of 'Jealous Guy', Brian shows us what a voice he's got. Beautiful. Watch this... then watch John Lennon's version that came much later and tell me which is better.

 

[UntilThen]

Now John's version.

I have a confession to make..

.. I have not been using the Auteur much after I got it back. There, I said it.

I have been seduced by da bass on the TH900mk2, it just makes listening to music.. fun. Another bonus of the TH900mk2 is that it is closed (or semi closed) and it allows me to listen to my music without disturbing my wife (or my wife disturbing me). However seeing that Zach had just joined the Glenn clan, I dusted off the Auteurs, plugged in the 2K cables and fired up the EL3N. And man, what a difference from the TH900mk2. Vocals sound fantastic with the Auteurs being smooth yet detailed at the same time. Mids are slightly forward and the highs are all velvet. Even though the bass doesn’t punch as hard as the TH900mk2, it still sounds really nice and coherent. I love listening to tracks from Shawn Mendes, Jody Chiang, Lala Hsu, Adele on the Auteurs, they just seem so full of emotion. Needless to say, the EL3N matches wonderfully with the EL3N, no noise whatever so and the background is as black as night.

I can’t help but think of this, the TH900mk2 is like Thor’s hammer, it has a sense of heft about it sounds and the bass is the main selling point here. The Auteurs are on the opposite end of the spectrum. They are super smooth and present the music in a comforting way, however please don’t confuse comfortable with boring as the Auteur entertains in its own way. Vocals, mids and instruments simply sound fantastic on the Auteur.
