Good morning High river, hope all is well with you today.the armboards are plastic as you say with 2 allen screws hlding them in situ onto the sub chasis, with a thin slice of cork, between them. the boards are deformed a bit and where the screws go, they are cracked, as if over tightened. I was thinking of replacing it with one cut from mdf, or , a friend of mine says he can machine one from a block of aluminium. also does the motor need lubricating. one more prob, when trying to play at 45rpm the belt keeps droping off.
Ps just read that maybe springs are getting tired, and to replace then with linn ones what dou you think
