Salut Dr C, (Dr C is a fellowcontryman)

You know the EIII i 've just bought : it's Damien Roque's one ;-)
He sold it to me with a boot issue... The problem is fixed, but now the stereo outputs are gone and there are a few more issues that need tender lovin care ;-)

Stero output, this is damn simple :

you have to solder a wire from the power harness, from one of the yellow wires, untill pin 8 of IC3 on the jack board. See pictures.

This provides +5V to the Jack board. This +5V is normally brought by one of the four flat cables going to the jack board, the cable A, wich is the leftmost one.


Be carefull !

ok, so i don't need to bypass the relay under the pcb as marked in another thread?

No, because if you bypass the relay, it will be like if there is NO relay, and youn will get a huge "PONK !" at power-up.

With the 5V, the relay is going to work !
