I bought one new back in 1986 just when it was first released. Within a couple of years the top plate had sagged and the PSU had blown up at least once (I think twice, but I can’t remember for sure, I know I had a world if pain with it). It was a fairly decent sounding deck of its day, but the build quality is sub-MFI IMHO, just hopeless. I bought it because it played 45s without needing to be disembowelled. I just wish I knew then what I know now and bought a really good clean Garrard or TD-124 for about 50 quid instead!
If looking to buy one second hand I’d save a bit more money and go for the later Xerxes 10, it doesn’t seem to have the ridiculous design flaw of the original (a huge cut in a piece of MDF) so it doesn’t sag in the same way, and I think they‘d learned how to make a PSU that didn’t blow up by then too!
PS Edit: damn, just re-read and see you have one! I’d not have been quite as rude about it in that case. Anyway, if its working ok and the top-plate isn’t bent beyond use I’d just enjoy it and be thankful you got a good one! I’d assess the rubber suspension ’blob’ things as I imagine they’d not be in that great a condition 30 odd years on. That, a fresh belt and a bit if a clean and I’d leave it be! One thing to be careful with is that the top-plate floats perfectly, if it binds against the outer ‘picture frame’ part of the plinth it sounds like crap. Similarly be very careful with arm cable dressing, as basically they didn’t think about that at all until they brought out the three-legged stands and suggested avoiding passing it through the aperture in the back of the plinth and just letting it ‘dangle’ down beneath. The Rega armlead is thin and flexible so pretty easy to deal with, I had one on mine. Just think about how it exits the deck and make sure it isn’t binding at all. The Xerxes absolutely isn’t a ‘plug and play’ deck, it definitely performs a lot better if you pay attention to all these aspects.
