I have a 1228 in need of some work can you hear any difference between it and a 1209 ?
The 1209 is a slightly heavier built machine - beefier motor (especially in the bearings - the bearing carriers are stamped steel, not poured pot metal), metal in lieu of plastic lever switches - AND - save normal cleanig and lubrication is the more trouble free of the two. The 1228 offers damped down cueing and (what Dual says is) a more refined gimbal mount tonearm. The horizontal mount bearings are the same, the 1228's gimbal offers vertical mount bearings above and below the tonearm, while the 1209 mounts both sets of bearing opposing each other below the tonearm. Gimbal sure looks neat & has SLIGHTLY better specs, but after all of these years, anything gets a little out of spec., so I personally feel that for normal listening & wear & tear, they're a wash. If I were going to a desert isle with one or the other, hands down the 1209 - it'll be running in 10 years without a hitch. 1228 may have some additional issues - the cueing needs to be re-packed (and the tonearm spartially disassembled to get at it) on an infrequent basis - the 1209 - a different system - no repacking is usually required.
