Monstros do Passado

Vamos lá mais uma vez e desta feito com um raro DD da Sony de 1976 o TTS-8000 que chegou a equipar os estúdios de rádio da BBC e ao que parece apenas foram fabricadas 2500 unidades deste menino.

Sobretudo o TB-2000, apesar de DD, deve ser uma máquina tremenda... com os seus 29Kg...!

Aqui, ao que parece, um TTS-8000 calçado num plint do TB-2000:

Muito interessante viajar pelas dezenas de páginas deste forum dedicadas ao "nosso" tema: Turntables & Vinyl Discussion

Amigo Zara o TB-2000 e o TB 1000 eram os plinth´s da Sony para este DD.

Onde estarão os quase 20Kg de diferença entre o TTS-8000 e o TB-2000?

As diferenças de peso estão nos materiais utilizados na sua construção.

Besides marketing, this is where Sony was, as ever, Sony : there were seven different bases made for the TTS-8000 !
Two were the official ones, three were pre-production samples and two were sold but never shown or advertised.
The official ones, TB-2000 and TB-2000, are based on that of the PS-6750 : a massive SBMC piece (Sony Bulk Mold Compound) is placed on a supplementary slab of compressed wood particles, the interface between the two being four enormous rubbery cushions with a guide so as to keep the two pieces perfectly aligned.
The maximum effective length of any tonearm on the TB-2000 is however set at 27,3cm - an SME3012 will not fit.

A TTS-8000 in its TB-2000 base makes for a hefty 40kg !
Dustcovers are of the unhinged type, obviously hand-made & hand-glued, and have to be removed entirely to play a record. When on, they rest on four rubbery dots set in the base itself.
In chaotic Sony tradition, a TTS-8000 in TB-2000 or TB-1000 base was not name PSE-8000, it remained a TTS.

Sound-wise the TTS-8000 is rock solid and very clean from top to bottom : where the PS-X9 is a tank à la EMT, the 8000 is more subtle and "musical", fluid, laid-back while still clearly being a direct-drive.
As silly as this may sound, the 8000 is like the best of both belt-drive and direct-drive slants.

OK, OK, a versão do meu post só pesa 40 quilitos...!

É levezito o animal !!!
