All user reviews for the JJ / Tesla ECC803 S

I rode there on my little Crate BV 120, a single stage in my preamp with three ECC83s always DD.
I tried the configuration with this lamp in V1 or V2, and I compared with 4 JJ ECC83s.
I do not think it necessarily have more gain, as they had told me, but it has a more biting and incisive that ECC83s "tighter" gain. We must know. IF this is the desired effect, it is a good lamp. I think it sounds better than V1 V2 as well, the receiver can benefit from the features of the first light (in my case, a ECC83s JJ, so more round and warm with a grain / gain more open ), while receiving the incisal side of this lamp. Then it is obviously a matter of taste.
For my part, I have not noticed any particular problem or microphonics breath.
I took my amp because JJ ECC83s give a more open sound, a runny hair (well it's still clean), round and warm, and it does not fit for what I do (stoner). However, I keep the lamp on hand if I had to do a Thrash!

installed today in V1 in my head Laney GH50L, instead of an unbranded loupiotte is very much a Sovtek. In V2 I also have a DD, but a ECC83.
Other tubes essays:
12AX7EH. I tried 3 or 4 that I have in reserve price. Too much background noise (may be not a very happy marriage with the ECC83 in V2)
JJECC83S: its too gloomy, RESULTING certainly a consanguineous marriage with his sister in V2)
Tung Sol 12AX7: its very right to gain lev and the background noise very acceptable. A bit steep for that GH50L adj sound bright enough (but what my forefathers gain !!!))
The JJECC803S offers a warm sound while offering increased over the DEFINITIONS JJECC83S. This is not a lamp High Gain far from it but in my case (I use my GH50L to clean even a big crunch and Lger distos are supported by a Blackstar Dist-X)) it served its merveille.Je recommend it to fans of vintage style sounds old Marshall and I recommend a pair ds as possible. You can never be too careful!
