Teac Tascam M-3700 K Fader ALPs 10kB10KD DUAL FADER

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

One side is a log side one is Lin, I believe this was usd with automation so one side a computer would know where the finder 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
