Hi, anyone know the effective mass of these tonearms?

There is no horizontal movement, if you engage the antiskate yes it moves outwards as it should, the tonearm hasn't been overhauled.

Many thanks



@@yogiboy many thanks for the precious informations. :)


Instead, is the effective mass the 309 are similar to 307 in your knowledge?


@yogiboy 

Perhaps the only difference is that the 309 has an overweight to add to the counterweight to balance heavy cartridges 

@roberjerman

This is a too easy match, but would an Ortofon MC 30 or a Nakamichi MC 1000 or a Sony XL 55 Pro, or a Denon DL 304 or a more recent cartridge, for example Ortofon MC 20 Supreme, be fine anyway?
How much does your DA 307 swing?

I did a test after taking it to the laboratory for a review, this and all that can fluctuate .... it seems to me to be a bit a little but not is possible improve.
I would like confirmation if your DA 307 also oscillates so little.

This tonearm goes with two different counterweights for MM or MC and can be used with both types of cartridges.
better this way
@luisma31 many thanks ... I will show your video to the lab for them to double check my 307 which does not persuade me a good job is done.

Does it have any movement in the horizontal bearings or is it fixed well?
Has your tonearm ever been overhauled?
