i should warn people, there are 2 versions of these.
one has a switching psu - as in the video.
the other has a linear transformer.
they look the same, it's just the internals are different.
i have a Duratool branded one here with the transformer.
it has 2 problems.
1: the transformer cant provide enough current to run the heater and pump together.
when you hold the pump on, it starts to pulse in rythm with the heater.
2: the pump is driven directly from the transformer via the socket, cable & trigger.
if you hold the pump on, the connector and cable warm up!!!

i'm waiting for delivery of a solid-state relay to fix this bs.
i suspect that's what's in the cable-tied box in the back of daves - a relay of some type.
