Rega tonearm for Microseiki table?

The model is MB-18.
Tonearm: low static mass straight
214 mm long
overhang 15mm

Any help???

Thanks again.

Russ,

The question is whether your RB250 will fit in the mounting hole and meet Rega's geometry. The RB250 is 239.5 mm long. Your current arm is 214 mm. That's a difference of 25.5 mm (or 1 full inch). The more important measurement is the distance from the arm pivot to the spindle. The RB250 needs 222 mm. You'll have to use a tape measure and see if you can get close to that number. The tonearm mounting hole on your MB-18 may be larger than the threaded bottom of the RB250. This is what I found in my DQX-500 and it gave me wiggle room to position the arm correctly. A Michell VTA sleeve allowed me to mount the arm in a hole that was too big. It also provides VTA adjustment. You can get these on ebay.

Jeff Spall offers more detailed measurements for RB250/300 arms:

Arm pivot to turntable spindle centre: 222.2 mm
Arm pivot to stylus (effective length): 239.5 mm
Stylus overhang (amount the stylus overhangs beyond the spindle centre): 17.3 mm

I hope this helps.

Mingles,

Thank you VERY MUCH for your fantastic help. You're the kind of friend that makes audiogon so great.

Russ, have you swapped arms yet? How did it go?
