Dynavector 505 to replace modded Incognito RB300.

I've seen this arm mounted on Oracle Delphi deck which has approximately same spring suspension as Michell. The spring suspended plinth of Michell is approximately 4kg, armboard for Rega arm is somewhere near a pound. What is the weight of so heavy DV505 than?

Czarivey, The weight of the plinth and the armboard, respectively, is irrelevant. What matters is the tensile strength of the springs that support the total mass. However, if you like I can weigh my DV505; it is currently not mounted.

Czarivey...one of my tables happens to be an Oracle Delphi
MKIV with a Zeta (van den hul) arm, which is pretty heavy.
I had to replace the springs on that table. Oracle makes
several different springs that are color coded and has a
list that lets you know which ones to use. I would really
recommend either talking to your dealer or send Michell an
e-mail and inquire. Lewm is right.

According to the Vinyl Engine the DV505 weighs 1250g.

Thanks, Mofi. I was going to have to hunt down my wife's kitchen scale and then try to balance the 505 on it, which would be tricky.
