I've posted on the Yahoo group but members with connections to the ''big name'' collectors are welcome to pass my pics on and help me identify the ballast.

You can't determine the correct voltage tappings by measuring with a multimeter and no lamp connected. A leak transformer inherently needs a load to provide the correct voltages. At turn on, the lamp is high impedance, the transformer core is not loaded and a high striking volatge is developed. As soon as the lamp strikes, the transformer is loaded and this pulls the voltage down to the operating level. A multimeter is not the same load as lamp.

Anyone got any ideas?

I'll exchange it for a lantern, preferrably MBF if anyone wants it.

Is this any help? Scan of the label attached to a GEC Z1622, 8-terminal leak transformer showing the various connections to the taps. Obviously later than your unit, but if that`s a GEC product, maybe it goes a little something like this:

Otherwise, afraid I`m out of 8-terminal ballasts to compare it to.

Well, thankyou for that. It didn't kill my 90w SOX lamp. Was a bright red but it was being sligtly overrun.

I've had it running for 10 mins and got my meter on the lamp terminals. 147v. Interesting.....very interesting though I doubt it's a ballast for 200w SLI lamps...:lol:


It draws 430w too so it's quite power hungry!!!!!

430w for a 90w lamp! It probably is a mercury ballast then. I'll have to see if I can find a similar installation somewhere to check on it...
