Hi Ampman, I also have a pair of XA90's. Years ago, I had issues with both sub amps, they were both swapped out under warranty by Snell with refurbished units. Now both of the replacements have issues. One hums and crackles badly and the other blows fuses. Please send me your info if you're still repairing these, or please tell me where I can find a schematic. Thank you, Kevin

Tomknow, I realize I may be coming in late on the conversation...but I have 2 90XA's also, and I've had the sub-amp issue more than once. I was able to send one of my sub amps to Snell when they were still in operation. They sent me a "refurbished" sub-amp in return, that had been repaired. Now, I have an issue with the opposite sub-amp; it either hums very loudly, or it blows the fuse when it first fires up. Yes, there is a fuse; it pops out just below where the power cord plugs in the back of the speaker/amp. I'll have to resort to finding a local electronics repair shop and hopefully find a schematic out there somewhere... Kevin
