Thanks, will try the solder joints before I start building circuits.

Any ideas for alternative op-amp chips for this kind of circuit?

Hi, First post so please be gentle with me.

Recently my RS924 stopped working in active mode, so I gave it a full rewire.  Still does not work in active mode.  I have checked out the battery (new), wiring connections and switches with a meter, all connected but still cuts out in active.

All wires on the active system connect properly and there is continuity through to the traces on the circuit board.

I considered making a new active tone board but I am unable to identify one of the components on the original, and can not find a circuit diagram for it.  The board is marked MP-EGF02.

Can anyone help? 

Pics show - Circuit diagram I used for rewire. Both sides of active tone circuit board.  The component I can't identify is the small glass item on the left of the nearest (bottom) capacitor in the top view.
