Tubes Asylum Questions about tubes and gear that glows. FAQ |
|
I'd like to know of your experiences on using the Electro Harmonix 7591's. I recently bought a matched quad to replace my failing 7591's. However, upon running it for nearly a 100 hours, it still sounded harsh. I checked the tubes using a tube tester and I found out that of the matched quad that I bought, one is less than 25% efficent, the next one has no reading, the third is 50% efficient, while the fourth one is still good. So of the 4 tubes, only two can be used. Is this normal or I'm just having a bad day.I'm currently using the tubes on a Scott LK72B stereomaster.
