Start with the easy bits. Just do some basic resistance measurements when disconnected from the mains. Firstly as the set died, with heaters and pilot light going off, this suggests something at the mains end so firstly, connect you meter, set to read ohms, across the mains lead between L-N and switch on. The meter should read somwhere between 50 and 100 ohms (depends on the actual transformer). Incidentally, if the set has a 13 amp plug fitted, make sure it hasn't taken out the fuse (you did fit a 3 amp didn't you)? If you get no reading, check the plug fuse and the on/off switch (single pole on these). If the fuse and switch are OK then check directly across the transformer. As this set uses an autotransformer, it's just one winding with a tap for the heaters. Somewhere around these parts you should find the problem.
There is very little else left that will make one of these go dead. The worst case is an O/C transformer but I would have thought that unlikely. Maybe the switch didn't like full mains.
