To be fair to Linn, the main problem was in using a wooden plinth with variable mounting blocks. Some earlier ones were soft and crushed easily, others were hard and didn't compress overmuch. yes, in the early days until 1991, I tightened up everything very firmly and this, with the P clip and arm cable correctly dressed, tended to make these early decks stable after a year or so. LP12's made since the early nineties were far better again, falling together in setup and only needing hand-tightness on the mounting block bolts (I could discuss the finer points with Neil for hours, but not tonight please ).
I agree about getting the Gyro and Orbe to work right (the Thorens decks were similar in this respect), but the advantage of these decks staying set up and "in tune" once done is so important to a non-fanatic music lover.
Marco, I do see your points above, but HFW is catering for a tiny enough audience as it is and although I don't know the figures, the number of interested Techie parties wanting to severely upgrade a now obsolete deck must be counted in the very low hundreds tops. No offense meant at all, but wild tweaks to the techie is small taties in the big wide world and I understand that the deck will not be made again once stocks have gone unless I'm very much mistaken.....
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
