If I were still collecting Vintage Japanese DD TT's the Victor Models will certainly be on my short list. The appeal is the mass of the materials, which has been selected for producing the Structure, certain Victor Models are looking like they are honed as design for the structure.
I have seen go to Japanese Vintage DD TT's with a TA > Cart' attached as sale item, be offered between £5K - £8K. Where the TT Model has a very wanting structure for the chassis. The Bowl which the Stator and Bearing Housing is seated, has a gauge of metal to form the Bowl of not more than 1mm (1/64). A very poor structure, to perform the role of remaining rigid, as all the forces of the driving the Platter and Platter Rotations are transferred to this structure. Flexion and Resonance are the only outcome.
My investigation of Vintage Japanese DD TT's has taught me there are models that are ranging in the designs put in place for the Bowl that mounts the Stator and Bearing Housing. Substantial material used to form the Bowl with a shallow depth for the Bowls form is the ideal for this type of design.
Additional methods adopted for any DD TT that functions to rigidly secure the Bowl, produces a design, if executed correctly, that offers a very good method to create an improvement for the mechanical function of the TT.
I am not too sure the use of the Original Plinth is going to yield the most attractive end sound from a Japanese Vintage DD TT. Research will show there are numerous redesigns for a Variety of Brands Models through out the period of their Hey Day of being in production.
The Link will show how ideas for the Victor Plinths has evolved over time. The Link also shows a Through Section of a Victor DD TT, the idea of rigidly coupling the Bearing Housing Base seems to be an easier option on this model shown, than some of the other Brands DD TT's I have investigated.
In the present era, looking into a Phenolic Resin Impregnated Densified Wood Board to produce a Plinth. Where using a Branded Product like 'Panzerholz', or a very similar designed Product from another Brand. Has for many adopters of such a material type, been proved through experiencing the material function as a Plinth. Shown to adopters of it, as a choice for a material. It has been the one that has created an end sound that is difficult to imagine can be bettered.
