Since Gibson bought Teac in 2013, their whole Factory Service Dept. in L.A.- ask me how I know- was let go and Service was given to a company next door to the Montebello address.They bill themselves as "L.A. Factory Service". They do not service to component level- board swappers. The Product Support/ Customer Service was shrunk to two guys- both well versed. The problem with contact via email is most of the people contacting them are for Teac consumer models where the owners are too lazy to read/comprehend the manual. This ties up a lot of time answering lame questions, while the more pertinent questions have to wait their turn- and yes, they are working from home.
