Beocenter 7700

16th June 2013

This music centre would only play a cassette for a second or so before returning to stop mode, with the winding functions being similarly affected. Since the tape transport was mechanically in good condition with adequate torque present on both spools the hall sensor 12IC14 was first suspected, but the presence of large pulses at 11P2-6 when the take up spindle was rotated proved that this was not the case. The real cause was 11C15 (10uF 63V) which was leaky, replacing this cured the fault. 11C17 (4.7uF 63V) was also replaced for good measure. [Beocenter 7700]
