Subject: Re: AJBR 20 disassembly -- I'm stuck
From: Michael O'Quinn (michael_at_oquinn.info)
Date: 2003-04-07


I forgot this one. You might also want to take a look at...

Look under Sound Improvement.

To quote: "I ended up removing the tabs, by cutting them with a Dremel
tool and metal cutting disc."

That's not something I was willing to do. Even though I do have the
Dremel and the metal cutting disc, I don't yet have the Dremel un-cutting
disc. YMMV.
