Rabco arms ?

I noticed tangential pickups in at least one other photo on this thread ; it strikes me as odd that broadcasters would use them due to their complexity , compared to conventional pivoted arms , given that the theoretical improvement in inter channel phase relationships ( and which some such as Russ Andrews would take issue ) is largely negligible in broadcasting .

They also can have advantages in lower mass ( particularly the B&O one ) but this is more applicable to delicate high compliance cartridges rarely used in broadcasting .

Curious .
