Last of the Technics RS-1500U series with much awaited silver looks, previously available only with the zzz-rare RS-1700US.
There's a trade-off however : no 26cm reels.
There's a bonus, however : the capstan/rollers assembly comes from the big RS-1800 / RS-1700U because of the auto-reverse function (1700U) and better tape path needed for the 76cm/s speed (1800U).
Bar the FL level display, the rest and specifications are like any of the 1500s & 1700s ; a digital counter was probably planned but not retained as, in '79, open-reel really was on its way out.
Added were a "rec mute" function and meter dim/bright continuous pot ; retrieved were the separate three-position bias/eq selector, (replaced by a single 2-position tape selector) and separate L/R monitoring switches, replaced by a stereo tape/source button. The auto-reverse mode selectors are next to the counter.
The RS-777 is a slimmed-down/slimmed-up version of a bestselling product which had passed in two short years from "star of the show" status to bulky and old fashioned.
Ah - I want one.
Until I can scan all the catalogs bought since posting this page, you can see better images here at Alkira Ota's website.
