Part of one of the last Wega-designed lineup, made with parts coming from Sony but circuit-wise developed in-house.
As all of Wega's 1970s output, design comes from Master Hartmut Esslinger.
The Modul 42V uses an enorrmous toroidal transformer inherited from the STR-7800SD, heatsinks from the same Sony vintage (cut in two and placed differently), 2x 15,000µF of main caps and two pairs of Hitachi 2SD675 / 2SB655 output transistors (12A/125W).
If filters, two-step loudness, tone controls, tape dubbing, LEDs and other 1978 goodies abound, the 42V also sports an MC phono stage, a four-gang attenuator, LEC transistors, an output relay and constant-current circuits.
Available in near-black and very light grey (Hellgrau - better) ; besides its pretty and extremely well-balanced looks, the 42V is a sound bolid : fast, powerful, stable, reliable.
The total production run should be of less than 4000 pieces ; the vertical racks are alas closer to Invisibilia.
