right channel problem
05/07/13 at 06:53:45
 
Hi!

I bought a csp2+ last year to complement my taboo and I noticed that the right channel is not as loud and focused as the left channel. The problem is quite subtle but it is definitely an issue; the sound seems to have dept only on the left, on the right everything seems 2d. The input and output pots are at the same position left and right, I tried to roll every tubes in the CSP2+ and the problem persists. When I bypass the CSP2+ and plug my source directly in the taboo, everything is fine, both channel sound great.

Does anyone have a solution?

Thanks!

Ok I just received new tubes that solved the issue (Phillips 6DJ8). So I guess my Electro Harmonix 6922's were to blame after all which is weird because I rolled them all and even so, the right channel issue persisted. Anyone else had a bad experience with Electro Harmonix tubes, is it a brand to avoid?

In general, new production tubes are overpriced compared with NOS tubes .

In terms of reliability, I'll stick to a NOS Russian tube if I'm on a tight budget.
Otherwise, any NOS American or European tube will both outlast and sound better than the New Production tubes!!!!

Electro Harmonix 6922's are supposed to be rugged. The key is buying them from a vendor such as Jim McShane who will test them and make sure you are getting a tube that is O.K.

www.cryoset.com offers them as one of their "super" cryo'd preamp tubes, in my experience a good thing.
