Originally i thought this was just a dual stereo fader and in  a way it is, however it turns out this is a very very rare Alps K fader.

I believe that one side is a log .one is Lin, I believe this was used with automation so one side a computer would know where the sliderr was and could move or record its position which would be more difficult with the audio log side

Used Main output fader, all have been cleaned but we warrant them to be fully functional

Used on the M-3700 and I guess many other units with automation
