Part of Technics R&B (recording and broadcast) professional line of products intended to be paired with their Technics EPA tonearms, a matching dedicated step up transformer was also offered MC-305 SU. When new the MC-305MkII wasn't cheap, at least 50,000 yen. Deserves to be matched with a very competent audio system. There is a complete review done by Audio magazine August 1986, check Ebay for copy listed.
