It is the same motor and controller as the 32 and 34. Just need to put a switch in the place of the jumper and take a look at what other switching is done. It would be the same as the 34 or 32.
Hello, bit of a long shot as this is super old thread,, where is the jumper on the servo board? I have a Tascam 38 and I'm very interested to get it to play at 7.5ips and this is the only reference I can find to doing that. Cheers!
