I'm attempting to replace the DBR cones with the Symposium Rollerblocks JR, but do date find it very difficult to remove the BDR cones from the bottom of the unit. This is because the cones are bolted on inside the unit, and in order to get to them, all the circuit boards must be removed, including all the mountings for the connectors on the back.
If anyone as any better ideas as to remove the cones, please let me know.
