JADIS DEFY 7 SPIT SPUTTER


I AM EXPERIENCING A SPIT AND SPUTTER SOUND FROM THE LEFT CHANNEL OF MY Defy 7 amp after it warms up for an hour. this is not tube related. When I change left channel signal tubes with the right channel signal tubes, the noise stays in the left channel. All other components in the chain have been checked out. Any advice would be appreciated. thanks

Jctubes is right, it could be one of a number of things. If it consistently occurs after warmup, it sounds like it could be thermally related. I had a similar problem with my JP80; it was a bad resistor. More likely, it could also be a bad capacitor. After they reach a certain temperature, they start to sputter and sound like they're sizzling when they go bad. These things sometimes are tough to track down, as the effect may only be noticable in a narrow temperature band. I'd suggest you find a good repair facility or contact Jadis if it's still under warranty.
Yes. Mike O'Keefe at Audio Outlet has a technician in upper Westchester or Dutchess County that he has referred his customers who own Jadis to, including me. He wasn't able to find the problem with my JP80, but that unit is highly modified and it took Andy Bouwman, the guy who did the mods, over 4 months of constant testing to find the problem, so I cannot fault him at all. If you call Audio Outlet, they may be able to help. I may also have the tech's number at my office, if I'm lucky enough to dig it up, but don't count on it....
Trelja's correct on this--there is one authorized repair facility in the US I know of, and he's located in Colorado, I believe. The importer has narrowed the dealer network considerably. You might also want to ask Lyric Hi-Fi in Manhattan, as I believe they are an authorized Jadis dealer or at least have been while Northstar has been the distributor. They may have a local recommendation as well.
One more possibility is Savant Audio down in Princeton, who I believe has a technician who can service Jadis.
