Another MG Head tube recommendation

post #1 of 8
Thread Starter 
In case anyone is looking for good tubes to "roll" with their MG Head DT, I have another recommendation. I've had these tubes lying around collecting dust for ages and finally got around to slapping one into my MG Head this morning. And, I'm reallllly enjoying them.

The tube is a 1950s Tung Sol 5751. It is a dual mica design (ala the 12AX7s), grey plates, and a D shaped getter. The sound is very involving. The strength of this tube is its atmosphere. And how wonderful it is. The sound is all around you - there are no "dead" spots. It also has that forwardness I like about the Sylvanias which I've raved about countless times in these forums, making it a great match for Senns IMO. I'd rank this puppy above the GE black plates, but alas still below my favorite Sylvanias whose focus and accuracy seemingly are second to none.

Nevertheless, by ALL means, if you stumble upon one of these Tung Sol 5751s in good shape, don't hesitate to buy it. Its one of the best tubes you'll hear in the MG Head DT, IME.

FWIW

I have one of these in my MG Head right now. It's a very nice tube, assuredly one of my favorites in this beast.

Okay fellas...where can I order one? I'm in Canada. My computers finally up again and I want to try some my first tube rolling experience.

I went to the tubestore.com but all they have is Brimar at $50.00CDN and Sylvania 7025 for $30.00CDN. there are other but most are Jans, Sovteks, JJs, Chinese, and thoe out of my budget Telefunken.

Are any of these worth trying? There's even less selection with EL84s

Look on Ebay. I wouldn't recommend the tubes you mention. NOS EL84s are $$$ and the bang for the buck is in the 5751s anyhow. I saw a pair of Tung Sol 5751s yesterday.

Pardon my ignorance on the tube front but what are 5751s. I gather they are an alternative?

hmm, better than GE black plates? must keep an eye out for those, then..I almost snagged a set of gold pin Sylvania 5751s a while ago before someone bid an insane amount of money for them. Out of curiosity, the EL84s I've been trying to acquire recently have all been in the sub-$60 range for a matched pair; how much did you have to fork over for those Bugle Boys? they're pretty hard to find..

Well, here goes another tube recommendation... The RCA Command Series Black Plates 5751 (2 mica) orange label... This is a very focused tube and to me makes even the Sylvania 3 mica black plate sound a bit fuzzy... It is also quite dynamic for a 5751 where I think the Sylvania has detail but lacks the weight which makes the music less emotional... The lack of weight makes the highs for the Sylvania a bit too crisp, what I thought was the biggest weekness of the Sylvania... The forward nature of the Sylvania also makes instruments sound closer together where the RCA spreads them around. Both are great tubes and I think both are worth a try.

Side note: Of course, the right tube is very system/preference dependent, and for me the Audience Au 24 (a continuous cast copper cable) really allowed me to hear what the tubes were about... Other cables had limited the RCA's dynamics and solid presentation, also depending on the source, making them sound a bit dark, too focused and small sounding and in those instances the Sylvania would be a better fit, where the forward nature and detail could be good... With the Audience, the detail and presentaion of the Sylvania just sounds unnatural, the RCA has lots of detail but not in an in your face kind of way. The Audience really allows the music to flow and come through, even outclassing an old reference, the Audioquest Diamond Hyperlitz, but that will be for another post.

I definitely prefer the Tung Sols in the MG Head DT to the GE black plates with my Senn HD600s. Definitely.

As for EL84s, not all Amperex tubes are the same. Not all the Bugle Boys were even produced in the same plant or even the same country! At any rate, the early D getter versions are what I bought and are by most accounts the best EL84s ever produced. I paid $100 for the pair which were NOS. I'm also interested in hearing a nice set of Mullard 10Ms and perhaps some of the Tungsrams. But that's about it in the way of EL84s.
