Hi and thanks OGD,

I did have myself a look at the pics and it looks as though I 
shouldn't do it any harm if being carefull around that ribbon. I was 
trying to 'pull' the glue :o ...but cutting the glue sounds like an 
easier way.
I'll be sure to clean the interior and jacks as well while I'm at it.
I'm fairly handy when it comes to simple as basic electronic 
repairs, but as far as the 'inner' components go, I wonder if Radio 
Shack has that level pot, or something to replace it with...? 
Replacing the piezo should be easy for me. Diagnostics of the little 
circuit board? Not sure till I take it appart, but I'm fairly good 
with soldering.
It's hard to see the circuit board in the pics, so I'll just have to 
take it appart afterall and do some exploratory surgery.
I bought this used, so I guess I'll just look at this problem as a 
learning experience ;)
