for sale is my rb251, Ive had it for ages and modded it with a couple of things
The arm tube has been drilled out to break up resonances, the wiring has been replaced with litz from vic at transfi, has had foam inserted and the external cable replaced with one made with 4 core mic cable with the screen acting as the arm ground to shield the wiring from end to end.
The wand has been resprayed in silver.
The arm has a standard din socket in the end of the arm post rather than the usual arm type as i wasn't about to pay out a fortune for a socket when i rewired it, and the cable has the corresponding din plug on the end.
haven't used it for quite a while, and is surplus to requirements as i have a formula 4 and an acos gst1.

150 quid if anyone is interested
