If you don't mind purchasing a minimum quantity of 55 gallons, I know a good substitute for the factory spec Linn "Black Oil" and it'll only set you back one-third of what Linn would charge for the same amount.The thousands of plastic vials to put it in would be extra,tho.
Any Subs Linn Sondek Oil 1,000,000.00 a gallon
Linn sells the bearing oil for $ 5.00 per thimbal full .Are there any techs out there who know what its made from ? Can You reccomend a substitute ? PS The Linn Lp-12 Rocks !
