Hi !

I mean I soldered a wire on the cristal metal
case ( be careful do not exceed 4 sec to avoid cristal damage)
to connect it to the ground.
It's better to avoid parasitic capacitor...
So I have a " 3 leg cristal ".

Hi Nomdi.

What crystal and what groundpoint did you use?

Hi !

I use this one http://item.mobileweb.ebay.fr/viewit...d=400231819515
This is standard cristal.
I simply used the central pin ground connection
of the stock oscillator.

I think Peter mentioned something much earlier in the thread about using a couple of twists of wire to add a little capacitance....

So just to be clear.... you soldered one side of each cap to the crystal body, and the other side to the 2 outside pads on the board?

Yes that's it !
And the cristal body becomes the central pin as with the ceramic resonator.
Sorry I forgot to take a picture...

Finally the picture ! sorry for confusion...
Cheers

Hi, apoligies if this has been answered but it's a long thread and I've read most of it and Peters condensed version.
I have the parts from an EZ51 which has a different display pcb.
There are 3 grey wires and 1 orange entering a plug marked led led sync sync.
with a legend saying it goes to the main board.
Could anyone please say what I do to these wires, if anything

I don't need to cut down the board.

Hi J Baldam.

It looks just as mine.

I cut the 2 rightmost ones down and the grey nmbr2 goes thru a pot to tha lowest connectorpin on the flatcable connector. I took the orange one to the left/most downwards connector of SW706 ( the most right/most downwards switch (repeat?))

Hi, thanks for the reply,
Right I discard the 2 right grey wires.
I connect the remaining grey to the lowest pin on the outside connector row.
The orange goes to the repeat switch.
Think I've got it but the grey through a pot

and could you please tell me why this has to be done

cheers

I have a potentiometer so I can decide how bright the led should shine - 1K in series. Well, pot and pot - there are kinds for different occations I guess
