Completely agree with you that the 6AH6 and 6AU6 families are among the best driver tubes for the LD amps. Just finished the 20 hour burn in for my two Sylvania 6AH6 tubes mentioned above on this page. There is none of the Sylvania brightness and these tubes are excellent all around. (Actually these tubes emerge as slightly dark sounding.)

 

Based on my experience I would say that you should try both the EF92 and the EF95/2-7 strap settings on those tubes that can be used in both modes to see which setting sounds better to you. My pair of TS 6CB6 tubes sounded much better on the EF92 setting than on the previously tried EF95/2-7 strap setting. (I was going to relegate these tubes to my pile of "tried but not true" tubes with the thought of eventually selling them, but now I am definitively keeping them.)

LOL - this is a very civilized forum; the only shooting we do here is to shoot for the stars to get the very best listening experience....beerchug.gif

 

 

Cheers
 

 

Hi Mordy,

yes, EF95 and no 2/7 strap. Theoretically, a hanging grid seems not the best case scenario. However, for some tubes families people worry, for others they don't and there is no (negative) experience in running heptodes with the EF95 setting. The sound is just best at that setting for my ears and I wouldn't want to sacrifice it due to the technically sub-optimal connection.

I've got a crazy idea.

I saw these the other day and I'm really intrigued. I have yet to see other Tung Sol 8425 tubes and while they aren't Tektronix tubes, they've got to be pretty interesting.

There are 30 of them and the total cost is going to be at least $82 shipped. That works out to about $2.73 USD each.

What if we pooled money into one PayPal account, bought the tubes, had the tubes delivered to one person and then that person would mail out the tubes to whomever had bought them.

Risky indeed but I know myself to have great integrity.

 

I suppose it also creates the question about other, similar tube purchases where there are packs this size and larger available and more than one person is interested in them yet does not need 20+ tubes to themselves. With the rates we're chewing on tubes around here, sleeves of 5 are perfect for me.

 

Just a thought. We've all been praised for the civility and thoughtfulness of this thread and it goes to show who it is that is currently making this thread stay alive are people of some integrity and kindness.

These are quite nice right out of the box with the 6DK6 being brighter and louder. At least they are both Sylvanias....

 

I could go on with the galaxy swallowing sound stage, the shimmering endless decay highs, the book shelf rattling bass blah blah, but I think it is more prudent to wait for them to burn in...atsmile.gif
 

Hi mordy.

 

Am wondering what your final impression was of the 6DK6s - your eloquent description above seems to apply also to the RCAs (used) I have just popped in. To my ears (and with my equipment, of course) they seem almost like the magical TS 6485s but with more bass...or am I deluding myself?

 

Anyone else tried these tubes? Would love your comments also if you have...

A number of us tried the GE 8136, which is a special version of 6DK6. You will find some impressions starting on page 55 post 815. I suggest you search for "8136" in this forum.

post #1355 of 5877

When I first wrote about the Sylvania  6DK6 tube I did it more tongue-in-cheek as a joke and used a very exaggerated language trying to be humorous.

 

Now I realize that the people on this forum are very serious people who are truly searching for the truest listening experience so I realize that I have to be careful in expressing myself very clearly. Even though I wrote blah blah after the description and added a grinning emoticon I realize that some may take me seriously about a tube that I wrote about before even giving it time to burn in.

 

In another post I explained that I now believe that I cannot truly evaluate tubes in the best way by listening to two different ones at the same time (unless they are very similar in their sound signature).

 

I only have one Sylvania 6DK6 tube. I am now listening to it critically together with a 6AG5 Sylvania tube. They sound very similar. For the 6AG5 I am using the E95 setting, and for the 6DK6 the E95 2-7 setting. (The splendid MKIII can take it!)

 

Both are fine tubes with a very pleasant and  natural presentation without any obvious faults. However, they lack that "wow" factor and don't induce that toe tapping stage where you forget about the tubes and just listen to the music.

These two tubes are very good but a step or two below the best 6AH6 and 6AU6 tubes.

 

Hypnos 1,

 

If you find a set of tubes that you are really happy with those are the right ones for you. Tubes react differently to different equipment and people have different tastes in music. What we are trying to do is to find a selection of excellent tubes, and then people have to find out what is best for them. In addition, there may be one brand of the same tube that sounds better to you than another brand of the same tube. (Tung Sol vs Sylvania vs RCA vs Mullard etc.)

 

Even though there are many variables, it appears that it is possible to get a consensus on which ones are the best choices.

 

What you hear is what you hear. Nobody can take that away from you, and you are not deluding yourself. Sometimes it takes time to come to a true conclusion about what you really like. The initial impression may fade away, and you may realize that something bothers you and switch to something else.

 

Happy tube rolling!

Very well put Mordy. +1

 

It is probably like your re-discovery of the 6CB6 tubes using the EF91/91 jumper setting. I was so glad I tried the EF95 setting for the TS 6BE6 again. Actually, I realized I found something important to me. Also, I noticed the tubes glowed stronger using the  EF91/92 setting than with the EF95 and I had a slight hum on one tube on EF91/92, which disappeared with EF95.

 

Humor is great and also makes reading more fun! If it is the description of a tube, only make sure people understand its an exaggeration. :)

 

OT: Mikelap, you got the HD800. Congrats! How do you like them and did you dare yet to plug them into the LD?

Thanks for the encouraging words. I am slowly recovering from Trioditis and Audiophilia Confucia, but finally found the right antidote: Tektronix Westinghouse 6AU6A/4825A.

 

Clarity, texture, timbre, liveliness, microdynamics en masse, involuntary toe tapping. C L A R I TY

 

Feeling good

Hi mordy.

 

Many thanks for your considered reply - have now got a handle on the wonderful humour that is shared on this great thread...please, PLEASE do not change! It is something that adds a welcome and precious ingredient to the vast knowledge, experience and enterprise shown by an invaluable bunch of guys. Stay as you are, I implore you.

 

Re the 6DK6s methinks I may have been seduced by the bass response first of all, and then made the basic mistake of not trying different genres of music. Time also must play its role, yes...

Will enjoy seeing how things develop - all part of the rolling game, n'est-ce pas? I do appreciate your wise words, mordy...

 

Gibosi.

 

Thanks for the info on the 8136s.

Once in a while I stumble across "6AH6V" tubes and I have been wondering how these differ from standard 6AH6. Casually searching on Google hasn't turned anything up... Does anyone know exactly what a 6AH6 with a "V" is?
