Hello,

Would anyone here have the mounting diagram (with exact dimensions) for the TTS 2500? I was an owner of the Sony PS 2250 some years ago and was about to do a replinth. Unfortunately I got busy and ended up selling the turntable to a friend. Now I have recently acquired a TTS 2500 without a plinth and am looking to build one. I saw the diagram in Viny Engine but it wasn’t up to scale. I was wondering if anyone has a pdf file of the correct diagram so i can just trace it on the wood? Also, would a Sumiko Premier MMT be a good arm for this deck?

I’ve had several but always went free-hand. So I can’t help you with the diagram. Iirc if you keep goggling under both models there is another source aside from VE. Fwiw, I found 2x 49-ply plywood on cones my ‘best’ plinth.

The Sumiko is a very capable arm. It was made by Jelco. If your arm is okay, then you would have to very lucky to find better.


Cheers!

Thanks! It ‘ll be my first time installing a tonearm to a DIY plinth. What measurements are important to take note of in terms of the tonearm’s placement? Do I just make sure that the spindle to pivot measurement (221.7mm in this case) is correct and that’s it?

Yes, but if you are using the hood, lid, remember to compensate for it opening and closing without disturbing the arm’s counterweight.

Cheers!

Anyone directly compared a bone stock 2250 to their plinth modded version (but same tonearm/cart)? 

I have a stock PS2500 with Grace G-840 running a Grace F-8F Shibata, a fine TT in it's own right. I recently completed a JN style 60 lb. plinth with Grace G-840 running a Grace F-8V body an with RS-8U line contact stylus. Both cartridges deliver very flat response and very good bass.

The improvement is significant and unmistakable; greater authority and clarity, broader and deeper soundstage, very defined and present bass, and great detailing and separation of instruments. Play classical music on the stock drive and you hear the orchestra, on the heavy plinth you hear the instruments. Piano, guitar, drums and vibes all sound authentic.

I've always found the term PRAT difficult to define but comparing the two provides a very clear example of what it sounds like.

Great to hear about this comparison.

I finally found some time to finally work on my TTS 2500 (Japan version of the 2250). With the help of a woodworker friend, here’s my Sony on a solid Narra plinth. The plan is to stain it in a reddish hue in a piano finish.The tonearm is a Sumiko Premier MMT.

Outstanding and a great arm too!

Cheers!
