If you like your linn, all I would do is replace the cartridge and get a new set of springs and get the table up and running. After that you can research the newer upgrades and decide what you want to do, if anything. Those old Linn/Ittok combos were very good when properly set up and, IMO there's no need to rush into a bunch of costly upgrades at this point.
Repair Linn turntable vs buying a different one
Dear turntable experts:
I would very much like you opinion and recommendation if I should go ahead with repair my old Linn LP12 turntable system which has Karma cartridge and Ittok tone arm. If the repair job include replacing with Krystal cartridge and Akito tone arm plus Linn cable and other misc parts, the cost of parts is about $6000 plus labor, with estimated cost of about &7000 total. Would there be advantage of proceeding to do the repair of the Linn turntable system vs. buy some other turntable at equivalent of $7000? Thank you very much.
