Although the value is not critical 0.1uF would definitely have been too low. Somewhere around 4.7-10uF is about right for most valve-based ratio detectors. Too low and you get distortion (particularly bass notes), too high and it is difficult to tune because it responds too slowly to changes in signal level.
