It is probably a good idea to upgrade!!! Musicians Friend just had a great deal on the Roland R-05 for $89.10 on Black Friday. You might want to look into some 24bit options instead of dumping money into older technology.
Thanks for everyone's help with this issue.
I ordered a couple of batteries off ebay, and installed the first this afternoon. Took me about 20-25 minutes, and everything went back together nicely. The H140 is now charging and all appears OK. I will use the second battery for the H108.
There are a couple of reasons I don't want to ugrade my iRivers/JB3s:
I am in the habit of repairing / replacing parts when they wear out, for something I'm happy using. Probably the same reason I run two 25 year old motorcycles, they give me more pleasure to use than the more modern (but probably more efficient) updated models.
The computer I use to work on recordings is from 2005. It has a hard drive of just 160GB, which means I am constantly backing up shows once I have finished them on two external drives. I doubt 1GB of RAM could cope with 24 bit recordings, it's slow enough as it is with 16 bit.
I don't have the playback facility, or been convinced that for the live recordings that I make, 24 bit would be of benefit. If you guys think it's so much of a leap sound quality wise, I'm happy to listen to what benefits there would be.
Off to download Foobar to listen to some 24 bit recordings a friend sent me, of a gig we both went to, sat 10 seats apart, using similar mics to those I recorded with.
Cheers,
Humbug
