At the time the K145 came out the only full size magnets I'm aware of,besides the K151 that came out at the same time and is different, were the 11 lb 1.2 G
assy on the d130 and the 19 lb .9 G assy on the LE19A then the K145 has a 19 lb assy with .9 G in the gap. is this the same? Obviously the frame is deeper but I'm talking about the motor part.
