Looking for some help here. I have inherited a Burmester 069 which I am going to sell. Only issue I have had is that it came without the power supply. I want to test this unit before listing obviously but have had little to no luck finding anyone in CA with a similar unit that I maybe able to hook up to a power supply and make sure all is working well. I could ship to Germany but the costs involved are beyond me at the moment. I am in the Los Angeles area and hope there is someone kind enough to help out. Any suggestions would be most welcome. Many thanks!
