The result was some bangs, maybe three and a dead BM 6500. The main fuse was blown but that did not resolve tho whole issue. When I connect the BM to mains the BASS, TAPE 2 and TIMER OFF are lighted and a small spark is seen from a relay unit under plastic cover. These are only signs of life in the BM in addition to the normal humming from the transformer.</p><p>Is there anything I can do myself, should I give up and take the unit to repair shop or or is&nbsp;the unit&nbsp;irreperable?</p><div style="clear:both;"></div>
