Got a Garrard 401 motor unit from Ali Tait a few weeks back .. finally as of today it's now in its plinth
Arm is an AT-1010 sourced from Jerry (originally from phonomac I believe), with an AT-7V cartridge (superb low compliance MM) from mad-moon. Fitted in the original heavy AT headshell this is an utterly perfect match for this arm - synergy indeed. Tonearm cable is one I had kicking around from Audio Origami. The plinth came from Austria/eBay, very modestly priced for the quality.
Motor unit needs a bit of TLC, it lost some bearing oil on the way down from the Auld Country, I've topped it up but will give it all a good clean out when a new gasket arrives in a day or so - I think it needs a good bit of running, the wheel is a bit noisy/uneven but I suspect that will settle down with a bit of play as the rubber seems OK (not hardened or anything) - maybe just needs to spin for a while after a period of not being used.
The sound has been getting better and better even in the couple of hours of play that it's had - reminds me of everything I like about Garrards, full in the bass, very musical, enjoyable. The big surprise has been the arm. It never seemed that happy on the Technics it arrived on but it's just right here, it's a really lovely, high quality thing, beautifully made and engineered. A real sleeper I think - at 16g mass it must have been a bit of an anomaly in its era, coming out just as super-lightweight arms and high compliance cartridges were all the rage, it must have been hard at the time to partner it optimally as all the big name 'favourites' were high compliance, this needs something in the medium-low compliance area.
Garrard bolts came from eBay, and from the local hardware store a hole cutter to do the armboard, and a tubular spanner to do up the nuts ... I don't know if this minimal bit of effort really qualifies it as a DIY project as all I've done is assemble it, wire it up, and set it up. Nice bit of fun though and an interesting contrast to the TD124 MkII.
