Tascam 388 Reel servo PCB 52101740-01

Audio Proz Inv #: 61743

Be aware this board is the most complex to calibrate. It controls motor play tension, speed as well as rewind tensions. Those controls can be a little “interactive”, often requiring a few attempts to make all adjustments properly. So it won’t just work correctly upon simple installation. The board is sensitive to the issue as described. Often the board itself is not bad but the power supply voltage is not running correctly. This is often due to loose or bad soldering or connectors at the main regulator circuit which must be looked into. I have seen In my experience this is a very common problem with the 388 if not addressed.

I've been offering consulting help over the phone about how to correctly service and diagnose these and other vintage units. What I explain is very important information that bust be investigated to make the unit more reliable, quieter better operation. I do charge a ˝ hour labor. Concerning the servo board, in general it is best to set the trimmers to positions similar to your original board (unfortunately these often have become mis-adjusted during a service attempt). 
Contact us at sales@audioproz.com   or call directly 617-926-8020  (weekdays 12 noon to 7pm no Tuesday)

Two variations of these boards exist but they work the same. One board has two fewer trimmers in it's design. To complicate matters worse … is the fact that in the manual explaining calibration; I’m convinced has two designated trimmers reversed in the described procedure. The opto sensor in the tension arms do get off spec and can fool you during calibration attempts. So it‘s complicated.
