I have the pheonix engineering tachometer and PSU linked to my 301. I dont think you cant buy them anymore as I think the website is down and the chap making them refused to export to the UK for a while. It's the best piece of kit I've ever seen to regulate a Garrard 301, mine runs withing 33.333 rpm +/- 0.001 - 0.003 rpm
