One turntable with two arms, or two turntables with one each - which would you prefer?

This 7 layer JVC Victor CL-P2 Plinth is what I have.

Two Removable Arm-boards, normally 2 arms.

It fits JVC Spinners: TT61, 71, 81, 101 (don’t go there). I chose TT81.

Three Arms:

1. rear 9" Removable headshell, various cartridges, MM, MC, ellip, shibata, ML ...; Arm has VTA on the fly for easy cartridge height changes.

2. right side can be long (mine is 12.5"), best MC cartridge, fixed..

3. Then I found a compact Mission arm with a short counterweight section and ’squeezed’ it in, for MONO ready to go.

the mission arm is made by Jelco, there is a Jelco matching model, and you do not need the mounting plate, just mount the round base ring, 3 screws.

Luxman Two Arms, PD444

I just helped a friend acquire and set up one of these

He looked at this PBN GrooveMaster

I talked to Peter at PBN, he will make a second tonearm board and metal cap for it.
