Trouble with trimmers

Trouble with trimmers

2012-04-07 by Jussi

Hey

On my CS80 the 16' trimmer of OSC 3 has come loose from it's tabs.
That is, the tabs themselves have lifted off from the pcb. :(
I'm not afraid to fix it myself, if I only knew how.
Is the fix difficult enough that I should have a tech take a look at it?

To top it off, I tried to take the card out and the damn screws feel like welded on! I'm afraid of spoiling them... 

Any help would be appreciated!

Looking at the pcb, I wonder if I could just solder a short lead from tab to tab following the traces? Then apply a drop of glue to hold the trimmer in place? Hmm..

Fixed it :) Short jumpers from tab to tab and some glue and it's working again!
