I don't convert the circuits.  I just toss in nicad packs that are 
plastic sealed and I locate them in a location where in the worst case 
scenario it won't damage anything.  As usual..unable to tell anyone in 
analog heaven due to the clunk head moderator who booted me for 
nothing.  Hate that. Anyway as long as people turn the machine on now 
and then the nicad packs last a long time and they're cheap often from 
All electronics etc.  -Bob
