Re: Electro Harmonix 6SN7

This tube has been a real disappointment..

When new, they sound absolutely fantastic - to my ears, probably the best 6SN7 I've ever heard. Problem is, after very little service, they start to show defects. Crackle, sputter, and other noise problems. We've had several support calls, where the issues were traced to the use of this tube.

It was rumored that the first run(s) of this tube had problems with cathode contamination at the factory. Newer runs may be better, and we have a new set here that we intend to try out.

I hope the issues are solved; the sonics of this tube hold great promise.
