Anybody know if it is safer to use a low milliamp (300) adaptor or high (1000) when the specs don't give you a clue. I am eating up batteries in my Korg Pandora and Tech21 Sansamp DI. They both are 9V. Neither of their web sites have any info on DC adaptors except that you can order one of thiers. I bought a "universal" one from Radio Shack so I could use it for both units. The guy there said when in doubt, always use higher millamp. The Sansamp's specs does mention that 100ma is the minimum, but no mention of the maximum. Any suggestions. I don't want to fry these things. I will call Korg and Tech21 and talk to their tech support, but wanted to check here first.
