Hi Tim,
I think I may have the same pot as yourself, is the box section that supports the pot rectangular ? unlike the later ones that are hexagonal. I've just replaced the pot, coil, thermostat and the lower platewhere the spout pokes through (got a bit close with the torch when trying to clear the pouring hole, coz it wouldn't heat up properly because of the knackered thermostat , but even with the little problems it's still good. had it ages, but still can't find the perfect setting
All the best
Baz
