After having been influenced by Art Dudley, I bought a Garrard 401, and did a DIY overhaul. I built a plinth that I love, put a Dynavector 501 arm on it, and have been enjoying it for years.
The 401's are not fussy, built very robustly, and sound great.
I have owned the Garrard 401, it is the TT that was able to move myself away from using the Belt Drive TT's. I do not recall the desire to try out other Belt Drive TT's in my system once moved over to the Idler Drive.
The 401 ended up seated on a '9 Stone' Granite Plinth.
A PTP Solid 9 is its replacement today but not its betterment, each have their merits in the realm of Vintage Idler Drive Systems. Each Idler Drive method, are also now able to be modified with a modern design approach where materials are able to be used that are produced with improved machining tolerances and potentially have a beneficial impacts on the overall function of the original design.
