Default Help in building a new Pioneer PL-12R Plinth

I intend building a new plinth for my recently acquired PL-12R. My problem is how to remove the (metal) deck assembly from the original plinth. I tried to access the deck from below and it seems the bottom sheet of plywood is glued to the wooden plinth.

The service manual (for PL-12D not R) shows a blown-up diagram of the various parts but does not describe how to elevate the top assembly (containing the motor and tonearm) from the rest of the turntable. Unfortunately I have already damaged the perspex lid during my attempt to remove the bottom plywood piece. Although this is not too much of a concern I don't want to cause any more harm.

Has anybody on this forum removed the top part of this turntable and if so can s/he describe how s/he did it?

Thanks in advance for your help.

The Pioneer PL-12R and PL-12D share common plinths and mechanisms. Perhaps these links might be of help -

Thank you very much musiklava79. Those two links are very interesting. Mr Ives Blog-post about the dismantling procedure is particularly relevant.

Thanks again.

Hi,

The links show how to free the topplate. I've rebuilt a PL12D
and a PL115D, the auto version of the PL112D. YMMV but
I didn't think a new plinth was necessary / worth the effort.
(Compared to the work needed on the deck proper IMO.)

Bitumen car spray internally and on the underneath worked
a treat. The plinth cleans up very nicely sprayed with car paint,
a simple coat of translucent top coat, leveller spray helps.

Paint colour is not critical given the "walnut" dark brown.

As brown uses all 3 primary colours you can use just
about any car paint colour, including brown on it.

5 Ways to Make Brown from Primary Colors - wikiHow

Just degrease it and spray topcoat directly on the vinyl.
Leveller (simply paint solvent) allows the skin flattening
of spray paint drying to repeat with no extra paint.

Black will give a darker brown, not pure black, unless
you use an undercoat, I wouldn't, the result is bland,
compared to the original shading showing through.

rgds, sreten.
