Is anyone using a universal AC/DC adaptor to power their CDBT2? The CDBT2 calls for 5volts but on my adaptor I can only select 4.5 or 6volts. It uses 4 AA batteries which ads up to 6 volts. Is it possible they put a resistor after the batteries to step it down to 5v so we have to buy the tascam adaptor (He said half jokingly.)? Thanks for any replies.
