JVC JP-V1000
JVC JM-S1000
JVC CD4-1000
(1977)

JP-V1000
is a fully-Class A CD4-compatible and SEA-equipped preamplifier,

JM-S1000
is a fully-symmetrical, triple-push-pull output OCL monster with a toroidal transformer,

CD4-1000 is a CD-4 demodulator with preamp facilities.

These images and partial specs come from a december 1977 german ad that is tagged JVC/Nivico but signed Victor Company of Japan.

I can't find any of these units in my japanese literature and I do not know if they only materialized as advertised prototypes. These three units were however shown "in the flesh" at the october 1977 Berlin Funkausstellung - the JVC tag on the frontplates indicates an export model as JVC only was Victor in Japan...

...so this post is a mainly call for info !
