plinth out of true

plinth out of true
ive got an old 1982 LP12.
I have recently had it serviced and all was well. I transported it home in the linn box.
when trying to set it up at home I put a fine engineers spirit level across all four sides of the plinth. It was out.
I worked out to get it true on the top sides, I would need to raise 2 corners 0.5mm and one corner 1mm.
I cut up an oyster card (like a credit card but slightly thinner and no raised areas) into squares, put one under two corners and two under the third corner leaving one without. I pressed down on the each of the opposite corners and heard a slight sound.
Now it sits perfectly flat.
The only explanation I can come up with is it was very tight in the polystyrene linn box and I may have inadvertedly pulled it out of square getting it out.
The old plinths don't have the corner bracing but mine looks to be in good condition (uk based).

Million dollar question - I'm probably going to get a circus kit and possibly a kore kit fitted, should I get a new plinth instead?
(I adore the existing grain, flutes, colour and patina on my plinth and it has much sentimental value)

any advice greatly appreciated

Hi,

A 1982 plinth does not have the braced corners and go out of true. Check for separated corner joints, you may need to glue them back into position.

Plinth is probably slightly warped and you might benefit from a new one. I don't think transporting it in the box would be causing this. Rather old age. Trying to straighten out a warped plinth, joining braces with glue is probably better left to an expert.

RE: plinth out of true
thanks

I know its probably sacrilege but with the deck now level again, could I get corner bracing fitted?

Not without taking it apart to route the pockets and it would probably cost close to the price of a new one. However, you could add the corner metal brackets that current models have.

What's important is that the 'playing mechanics' are all level, rather than the plinth. Interestingly, the 'plane of the 'playing mechanics' will vary with the weight of the record [and with the age of the trampolin, as the rubber at the arm pillar end tends to stretch].

RE: plinth out of true
Many years ago I had a beautiful Rosewood go out of true and in the end I sold it on. The new owner knew it was not dead flat but was happy as it would still outperform anything at the same cost. Sorry but the only real alternative is a full replacement but there again thats a fabulous adventure to have with all the various makes and woods available.

Back in 1982 the deck was just out of the era of being available as chassis only. Plinths were not considered as important as we know they are now, and it could well have been out of true from new.

Either live with it and treat it as a period pice or replace the plinth.

Hi Mickdale,

If you decide on a replacement plinth and don't have money to burn the following might be a good option,

Certainly seems to be good value for money compared to some that are offered around.

I'd agree. They look OK. They cannot be worse than a racking 1970s one, and the finishes look good. If they turn out to be below par you can send it back. Very cheap, but labour rates in Spain are amongst the lowest in Europe.
