"Don't wait. Join our modern adventure in musical appreciation !"


Extra-rare pre-Optonica amplifier still boasting about its all-silicon guts.

Rare features for such a vintage are present : separable pre/main terminals and full tape dubbing selector (1 / 2 / 1>2, 2>1).

Very elegant, too.

Made to be hooked to the dual-dial ST-511H tuner, the RT-727H open-reel recorder and RRT-442H cassette recorder.
