Did you try RCA 6AS7? GEC 6080 is easier to get. I have enough of it.

No. I still have 4-5 weeks before I get WA22. I am just doing my homework and trying to get the tubes before WA22 arrives on my door.

Should be. Mullard CV181 is one of the best. But at that price CV1988 or Ken Rad VT-231 is better bet. Ken Rad VT-231 is very dynamic, sound big, less smooth, but very fun tube. Try 6F8G, you would not regret.

I posted first in the "which amp for hd800" thread but figured its more on topic here.

I want so badly to know what you are talking about, but the more times I read this thread, the more confused I get...

Quote:
If you want take your WA22 to next level 6F8G is the key, as start now EML began to show weakness
?????? The 6F8G are drive tubes and the only EML product you are talking about is the 5U4G which is a rectifier... why are you recommending a drive tube over a rectifier, am I missing something??

From your first big post of impressions, it seems you ONLY tested the 6F8G with the Mullard 53KU/CV378 rectifier....... but then on Page3 you change your mind and say the Mullard 53KU/CV378 is crap..... but the 6F8G (and also 6FG7/6FQ7 ) is still good???

Well if you only tested the CF8G with the 53KU/CV378 (you didn't mention trying a different rectifier with them) and then you say the 53KU/CV378 is crap while the CF8G is still good.... please tell us what Rectifier tube you ended up using with the CF8G that was still good?

Ok I noticed you did say you tested the CF8G with the other tubes :

Quote:
I tried all the tubes above, notice there is something missing with EML, the "Impact". I listen to rock, so bass is important. All other tubes in the test kick hard, EML now shows its mellow botton end. the hight and mid just fine as with Brimar, but now from mid bass down just went soft, no balls.
The best match for this test is with Mullard CV378/53KU. It rocks as hard as other tube, at same time lost 2% of soundstage and air compare with EML. I think 53KU is more balanced.

Then on page 3:

Quote:
Correction: I misjudged the 53KU/CV378. that was a mistake I shound not use different CD to do the review, and should use old CD that I have listend 100+ times. They are not as good as once I put old CD in. I am very sorry about this, because WA22 sound so good, I often easily lost in the music. Still Mullard GZ34 offfers most impact, but sound cool, user beware. 5AS4 still hanging on good.

I ordered 5Z3 made in Italy, that is going be fun.

6F8G and 6FG7/6FQ7 I have used for long, the review is very accurate, do not worry.

I think what confused me was the "6FG7/6FQ7" at the end, when on the first page you said:

Swap 6F8G with 6CG7/6FQ7
So if 6FG7 a typo for 6CG7???

I used:

6SN7 > EML / CV378 / 5AS4 / GZ34
6F8G > EML / CV378 / 5AS4 / GZ34
6FG7/6FQ7 > EML / CV378 / 5AS4 / GZ34

I did try them all with all tube type I have. CV387 is OK tube, just not as good as other tubes. EML has its strength, and weakness. EML has lager soundstage, more 3D like soundfield, and better voice than any other tubes. It is weakness is bass impact. If you ever tried GZ34, you will understand. That's why I said if a person only listen to vocal, string, classical, and soft pop, EML is perfect fit. But anything have heavy bass, and you want impact. EML is lacking COMPARE with GZ34 and 5AS4.

5AS4 is very warm, GZ34 is cool, very dynamic and impact, Brimar 6SN7GT is very warm, EML is nutrual (tube nutrual, which means warm by SS standard), 6F8G is little less warm than Brimar about same as Ken Rad VT-231 more impact than 6SN7. 6FG7/6FQ7 is cool, but extension on both end are better, open sounding, and have crazy "impact".

Now you get a picture?

So, it is not good idea to pair 6FG7/6FQ7 with GZ34 with bright sounding cans, but HD650 can get away. HD800 may not. K1000 may not. Also it depend on CD, on badly recorded CD I call for 6F8G.


6FG7/6FQ7 are the same tube

Well Seamaster, I have some Raytheon 6F8G and Mazda 6CG7 tubes sitting here waiting for adapaters to arrive. I'll be really interested to see if our findings tally. Hopefully they should be here within a couple of weeks.
