Full Music Tubes - any good?

[Marco]

Guys,

I was thinking of trying these new 6SL7s, from Full Music:

More info: http://www.tube-fullmusic.com/products/en/6SL7_en.htm Interesting link, showing how the tubes are made: http://www.enjoythemusic.com/china_2009/tj_full_music/page2.htm

Does anyone have any experience of using tubes from this Chinese company?

The anode construction of the 6SL7 looks interesting, reminding me a little of that of an ECC35. If they were any good, it'd be an interesting alternative to increasingly expensive NOS varieties.

They do quite a range of different tubes, including KT88s, 12AX7s and 6SN7s:

Any input appreciated! :cool:

I have.

I´m using a pair of their ECC83´s. They are outstanding !

Think of the "mongers" you got a couple of weeks ago, they are not far off - definetely going places.

I can vouch for both sound and build quality of the 83´s, as for the other TJ offerings I dont know.

I bought a matched pair of TJ Full music 12AU7s(ECC82s) for a World Designs Pre 3, as I wasn't too keen on the sound of the pre with the standard issue jj valves, which I found to be very powerful sounding, a bit too hard and lacking character.

I took a gamble on the Full musics and wow! straight away the sound was so much sweeter, darker and much quieter, I can now use my volume control to it full potential, rather than before it was tooo loud at the o clock position.
With about 80 hours on them now, they sound even better.

For my ears and system the full musics were a staggering improvement and so far the single best upgrade I have made(that's saying something) Thoroughly recommend them if you need the edges rounding.

I have just ordered 3 TJ Full Music 12AX7s (ECC83s) for the WD phono 3, see how they go but I havn't got my turntable running yet so it may be sometime before any reports on them, but I reckon they will return the same results for the phono.

Hope this is of some use to you.

Cheers KC.

Hope this helps.

TJ's are very good indeed Marco, although starting to creep up in cost a bit these days. I don't have experience of the TJ 6SL7 but some of their other valves (12ax7's) are superb. The Brimar CV1985 is also worth searching out as are some of the Russian military spec 1579 6SL7's. I've also heard good things about the relatively inexpensive military spec Phillips 6SL7WGT's (available from Watford valves at £22 each).

Hi Marco - I hadn't seen your post previous to posting mine on the TJFM 12AX7 (in the wrong section I might add !).

As mentioned in mine I'd heartily recommend getting a price from Lorenz @ Wiwi tubes if you do decide to take a punt. Let us know how you get on.......

Truth is if I hadn't liked these I dare say I'd have got most of my money back here or on ebay.

[IHP]

So did you decide to order these pretty things then Marco ?!

[Covenant]

My wife is going to be puzzled when a parcel arrives from wiwi tubes!

[Ashmore]

Ha so would mine be, but I'm having them sent to work!

[Marco]

Not yet, dude. But they're on my 'toys to buy list' for next month :cool:

Hi Jerry,
You ordered one/some then for the HA10? (you'll not get the lid down if you try to fit them to your B-DAC) :lol: .
Dave.

No Dave, I was thinking for my Croft Series 7 but now you mention it, I might try it in the HA10. In which case should I order two?
You have got me thinking now!

[DaveK]

Hi Jerry,
Beat you to it :lol: (but sorry, never thought about you - ooops :doh: ). That used to doing my own thing, logic wise, I never thought about inviting you.
I have a valve buffer amp (from my favourite supplier ;) ), that takes two, so guess how many I've got coming - (the plastic has taken a real hammering lately :lol: ).
I can't recommend dealing with Lorenz high enough - the buffer amp requires matching triodes but not within each valve - triode A in valve 1 should match triode 1 in valve 2 and the same for the B triodes - ''no problem'' said Lorenz and I'll forward the test figures to confirm it.
Be interesting to swap notes with you after receipt.
FWIW Sean acknowledges that the valve supplied with the HA10 is the best he could afford within his target selling price but freely admits that he has tried other higher spec valves in it with greatly improved SQ - I'm looking forward to listening to what is already a bloody good amp.

[Covenant]

Actually Dave, I am not sure the 12ax7 is the same as the E88cc that comes with the HA10. I wish they would call them Agnes or Tracy or any name because I am prone to number blindness I think :lol:

Hi Jery,
Actually you are quite correct and I have had to rethink my strategy. It currently looks as though Full Music may not make the equivalent of the E88CC - sh1t!!!
Dave.

[Ali Tait]

Correct. ECC88 - E88CC, 6DJ8, 6922, E188CC and probably more I've forgotten.

[jaym481]

12AX7 is ECC83.

[Covenant]

I am still confused-is the E88CC the same as the ECC83? (If so you are laughing Dave)

[Ali Tait]

Nope. E88CC is a higher quality version of ECC88.

Jerry,
You may find it helpful to see this (and maybe print it off for future reference?): -

E88CC ECC88 [and their equiv] have a diffrent heater arangement to ECC83, so cannot be interchanged with each other without heater wiring correction.

Anthony,
Further to the above and possibly more of interest to others than yourself :) I understand E88CC, ECC88, 6922, 6DJ8 are all essentially different codes for the same valve. The 6N1P Russian valve is a similar valve but needs a heater current of 500 to 600mA while the other valves I list need a heater current of around 300 to 360mA.
On this subject, I seem to recall seeing a table, or series of tables, that listed all (or most) of the different code names for identical valves, but I have lost contact with it. Is it possible you could point me and others at a similar table for future reference?
TIA,
Dave.

[Ali Tait]

See here Dave-

Thanks Ali,
Once I'd worked out how to navigate it it gives a very comprehensive load of info - I've added it to 'Favourites' so I might be able to find it if and when I need it in future :lol: .

If you spot a tasty tube for the HA10 let me know Dave, maybe ask Lorenz what he would recommend?

Too late mate, already done this morning ;) - I'll keep you posted - if you choose to order we can add it to mine but, on second thoughts, smaller packages may attract less interest from HMRC and then there's onwards postage - probably conter productive :doh: .

No problem Dave, I will let you be the guinea pig.:)

[DaveK]

Gee, t'anks pal!! ;)

[vouk]

Hey Dave,

If I may, what did you end up ordering?

[DaveK]

Hi John,
No problem with you asking - in the absence of any other recommendations I plan to order your recommendation, the Amperex.
TBH I originally iordered the Full Music version, only to be told that Full Music don't offer that particular configuration, so I told the guy to put my order on 'hold' until I get some advice. If nothing else comes in, advice wise, over the weekend, I'll go with the Amperex.
Cheers,
Dave.

[vouk]

Won't regret it. I did some A-B comparisons back in the day on a Graaf GM 100 - to my ears the Amperex beat their Sovtek and Siemens counterparts by a mile. I am not familiar with he FMT valves - but for your needs try and stick to the 6922 types - their have an excellent reputation for linearity and signal/noise ratio, especially in the all critical voltage gain stage. :cool:

[IHP]

Just wondered if you got these Marco, after more time the 12AX7 I was raving about just get better, astonishing. genuine upgrade for £45 !
