I've had Technics decks get sticky brakes after a long time of non-use. This can cause the reel
motor to appear "frozen," but if you hold down the two top spring-loaded guides, then hit fast-wind
and start a big NAB reel spinning, that will usually un-stick the brakes. Then just run the motor a
while, both in FF and REW. Do same for both reel motors. Usually, that will cure the problem, but
sometimes the brakes will get gooey and then you need a professional.
Steve Smolian's suggestion is also very good, make sure all the heads, sensors and guides are clear
and tape runs smoothly. The person should check the whole tape path for crud and goo.
