Glenn, Xcalibur255, Clayton SF and john57, what is your favorite combo?

 

 

596 - TSBGRP

596 - 1633

596 - 13D1

5U8 - TSBGRP

5U8 - 1633

5U8 - 13D1

While the 3DG4 may not have the best sound-stage it does have one of the best clarity of sound and the soundstage is not bad at all with carefully done recordings. Many recording artists today tend to over mic the recordings. The 5692 and the round 6F8G for the drivers and the TS, Bendix and the GE (good value) for power.

3DG4

5998

13D1

 

In my 2A3 SRPP OTL I use the 5U8 because the B+ is 500 volts so each 2A3 can have 250 volts and the rectifier has to have

twice the B+ breakdown voltage and the 3DG4 can't handle this high voltage but the 5U8 can handle 1700 volts.

Interesting. Inside my listening room, the '596' has more clarity...everything over the 3DG4. But, of course, our systems are different among other things.

Well let me ask this, anyone's preference change from the OTL being in stand alone mode versus being used as a Preamp?

The more you post, the more I learn...

I really don't use it as a preamp I have a stand alone preamp that uses #26 tubes I feel the #26 direct heated triode sounds better then any 6SN7.

Now All my amps are all direct heated triodes I just love the sound of these tubes. They are a PITA to work with but it is worth the hassle.

Heheh, so I did get you on the 5998 bandwagon after all.  biggrin.gif  It's such a shame people don't know how good this tube can really sound compared to the 6AS7 when it isn't starved of plate current.

Gotta say 3DG4 - 5998 - TSBGRP.  My second choice of driver is still my Sylvania GT military plate heavy chrome top.  People who walk by this tube thinking they are GTA by mistake don't know what they are missing.  After that I would have a genuinely hard time picking a 3rd place tube.  The Brimar 13D1, Hytron GT, and Sylvania Bad Boy are all excellent and bring their own unique charm to the table.

 

I agree with john, the 3DG4 does not throw the biggest soundstage, sometimes I wish it were bigger, but it excels in many other things and has such great transparency.  If I could take this tube and give it the soundstage of a 274B it would be perfection in my opinion.

 

The driver is really the only tube I roll in my amp, I just don't feel the need to mess with the others ever.

If it has T-plates then the CBS should be a Hytron tube Clayton.

I have to say, my 5998's are holding on! biggrin.gif For me, the sound stage of the 3DG4 is what it is; not particular put off by it. This tube shows great promise. But in my system, the USAF-596 has more clarity. I'm sure there's an electronic influence floating about my system...but the 3DG4 lacks the refinement of the '596' to my ears. Perhaps, the brand I have? Maybe I'll buy another and give it shot. If you all are on to something, I'm not gonna wanna miss out! wink_face.gif

 

Yeah, I don't bother rolling out the 5998's anymore...the best in their slot!

Thanks. Here's some pictures. I also use a Zalytron. Any info on the Zalytron?
