Jelco St-250/Audioquest PT6 the exact same?

I have been googling around and have not been able to confirm that these are an exact match. I am getting a Jelco for my HW-19 mkiv and have to fab an armboard and mount the Jelco. I have found better templates for the audioquest and comparing them to the jelco instructions they seem identical but wanted to be very certain before drilling any holes.

thanks

They look the same but are different.

Most notably the ST-250 is not fluid damped. The PT-6 is (I have one).

They look very much alike but there are differences.

I also have an early version of the Jelco 250 here. The "body" looks the same but is different- the 250 is a sealed unit. The bearing housing is different- the Audioquest features a cupped concave dome on top, and possibly an advanced horizontal bearing assembly. I'll need to get back to this.

The arm tube- my guess is perhaps aluminum on the Jelco model and some hybrid alloy for the Audioquest?

The Adioquest is also damped with a rubberized sleeve.

Good to see you here, Mark.
