When it comes to Marti equipment, I've been very pleased with SRS Electronics, 1501 N Main St, Cleburne,TX 76033. (817) 558 0079. They'd be more likely to help you with something like this than BE would. SRS is quicker, cheaper & every bit as good as BE when it comes to repairs on Marti equipment. George Marti himself works there & he even answers the phone on occasion. I highly recommend these folks.
