copy , copy FWIW
I also have the Maha 9.6 but i think the akaline 9v gets better life. More reliable. I also have the Denecke PS-2 and also a sonosax pre running on alkaline rather than the Maha 9.6. Once the NIMH starts running low it really takes a dive. I know buying alkalines each time is a $$ but I like the reassurance of getting the show.
