Any Jadis Defy 7 MKII experts out there?


I have a Jadis Defy 7 MKII amp. The left channel was distorted so I took the bottom plate off to check the bias. All six of the bias fuses were blown on the left channel and 2 of the bias fuses were blown on the right channel. Does this mean that I have 8 bad 6550s or does it mean the bias drifted to the point it blew the fuses?

Any help would be appreciated.

Im no "expert" by no means but have owned a couple Defy7 amps.I would guess its the tubes,replace all them including the 12ax7s and make sure the new tubes are all matched(will be expense hence the reason Im no longer an owner).Also have the amp re-biased by someone that knows what they are doing.If that doesnt do it a tranny is going bad.
