I recently got amp. Either I lost or never had one of the magnet feet. These are the bottom part of foot that screws off for spike to be used. Searched net for Yamaha replacement but no luck. Would anybody know how to get something like that? Will try calling Yamaha but wondering if something else generic fits, if it is same part as some other part Yamaha or non Yamaha, etc. Would buy whole foot if I knew it had correct magnet foot.
