At mine (I took the picture posted of a thread in this forum)the lamps are mounted correctly, the leads from power amp bulb go to the power amp section and the leads from the pre amp bulb go to the preamp board !
Yes, both lights would be on when the amp was running. When I would put the amp on standby, the power amp light would go off and the preamp light would stay on. It should have been the other way around.
I also had a Twin Valve at the same time to compare mine to. The colours of the lights were reversed comparing the Twin Valve and the Hexa Valve. In my Hexa, it was obvious that the lights were reversed. I guess it was probably more likely that they wired it wrong, instead of having the front panel printed wrong. Maybe yours is different.
There aren't any schematics available for the Hexa, at least not that I or anyone else I spoke to could find. These amps weren't fully sorted out when they put them on the market. I remember that a Talkbass member that worked for the US distributor for Trace back then posted that they received 40 Hexa Valves in the US and only half of them worked, so there are less than 20 in the country.
