I just discovered this brand of amp on ebay, sold from HongKong but they don't say it... not cool.
Do you already know this page ? Otherwise, it is hard to find something about it ?

Can I ask some comments about it ?

I would get a better amp, the timester amp uses tubes that are not accessable.
you know those two small tubes in the front,

good luck finding a replacement for them, the website states its 5670 which dont work on this amp.

Ive tried 3 different variations all of them dont work.

which means Im stuck with the stock tubes and when they burn out, the amps worthless.

I think you're looking for the wrong tubes.

is that the same amp you have?

EDIT
If it is, Shanling uses the same tubes, the 6N3's, in their CDT-100, I'd contact a shanling dealer to see if they have replacement tubes.

this guy seem to be successful changing the chinese tubes to the russian NOS

Like what other had already said, you are looking at the wrong tubes. The T-200 uses (2) ECC42 (European designation, US equivalent is 6CU7) as signal tubes, and (2) 6n14n (Russian, European equivalent is EL84 or E84L, US equivalent is 6BQ5) as driver tubes.

All these can also be substitute for the 6n14n/EL84:
7189(A), 7320, CV10321, CV2975, CV8069, N709

There are probably some other substitutes for the ECC42, but I am not familiar with that tube. Best thing is to check with the manufacturer to make sure the substitution is OK.

as the timester site stated, this amp used 5670 tubes, are they wrong?

anyhow these are the tubes I used and all of them wrong

5670 ken rad NOS
5670 GE NOS
6cw7 NOS
Ec84 NOS

Zero success and a pretty good amount of money down the drain.

I think he is referring to the el84s (larger tubes) I have Russian NOS in them right now.

The smaller tubes dont work.

RnB, check out these tubes from Quest For Sound, I got them for my Jasmine T-200 and they are working fine.

Compared to the stock tubes, they are more focused & dynamic. The switch to NOS EL84's made a bigger difference, but these did help as well.

Overall, I think I have invested just under $400 in this amp. Is it worth that? Don't know, can't compare to other tubed amps, as the only one I've owned is the RKV-MK II, and that's in another league.

But this unit drives the Sony SA-5000's and the Grado SR-325's VERY nicely. No complaints at all in sound. I DO have a tiny bit of hum, consistent in volume, and not in the way when music is playing.

I have also tried the Jasmine with headphone output driving the AKG K-1000. It managed to hold its own, though the K-1000's lost some life. I haven't tried it from the speaker outputs, and I also have a small pair of Fostex 4" horn speakers in my basement that I still need to pull out and try with the T-200.

Sorry to babble, but bottom line, check out the link....

Thanks,

EDIT - PS - My Jasmine said it uses 6N3-type tubes, that's why I got the ones off A'gon....

I have a Sophia Electric Baby Amp that use a pair of 5670 as well. I bought a pair of Northern Electric 396A tubes that are similar to the Western Electric ones while they are cheaper than the WEs. I don't have a chance to compare the two to see if they sound identical though.

I have the Jasmine T200 and I replaced the output tubes with NOS Russian EL84. Works fine. It improved the mids/voices, maybe a tiny bit more detail but a tiny bit less bass. The original Chinese tubes are really not bad. I'm going to get a few more tubes to experiment. I read a comment that the Electro Harmonics are supposed to be quite nice.

For the input tubes, I just bought a spare original Chinese pair from the store where I bought the Jasmine so I'm covered for a very long time.

I love this little amp and I finally use it more as a speaker amp then a headphone amp. It can drive speakers very well to a volume level that is fine.
