Hello folks,

I need to change the speed setting on my Otari MX5050 Bii-type reel-to-reel deck from 7 1/2 ips to 3 3/4 ips. Currently the unit is set up for 7 1/2 and 15 ips, respectively. I have found instructions on how to do this by opening the unit and manually selecting the alternate position of "Switch S1." However, I cannot locate said switch inside the unit as instructed.

Any insights, comments, diagrams, images, etc. would be appreciated.

Cheers,
