Revox A77 reel to reel 2 track tape recorder - 3.75 & 7.5ips. The machine is in working order and all the functions operate correctly - play, record, fast forward and rewind, tape auto stop, VU meters, tape counter etc.
Whilst I've owned this A77 I have replaced the reel motor bearings with new SKF bearings and calibrated it for Maxell UD tape (using a professionally restored Ferrograph RTS2). The power supply delivers the correct 21v and the speed has been calibrated using a frequency counter.
Cosmetically the front panels and case are in reasonably good condition although there are marks and scuffs from use.
