I should probably search the archive, but has anyone experience with RA90's? I got one recently and when I powered it up (after a thorough cleaning) it faulted with E9. I have (thankfully) several manuals for this device and it seems to indicate the solenoid which "pulls the pin" on what looks like the voice coil head motion thing may be sticking. "head motion thing" - that's a techinical term. (ok, if you must know, I bought it on ebay, but for 2 orders of magnitude less than the truck full of pdp's :-) I've decided that I like RA90's better than RA81's :-) mostly because I can lift them :-) The drive spins up and I can run the diagnostics. The simple tests work. any thoughts? -brad
