Re: Synchronome contacts pitted

Hi all,
i've just brazed an AgNi contacts to the armature screw with a bigger 3,5mm contact diameter, this give me a 9,6 sq mm contact surface area (5.4 times the original) to deal better with pitting.

Also placing a diode across the coils (slave and master) for greater effective spark suppression leads to increased contacts longevity, original resistor is not so much effective in spark quenching .
