I've quickly read through all the posts prior to this one and I didn't see what follows below - so I'll mention it now.

In my opinion, two essential tools for a general electronic repair workshop are an isolation transformer with a 1:1 ratio and a Variac - inter-connected in that order, not Variac then isolation transformer - with suitably rated fuses: one for the incoming mains to the transformer and one on the Variac output. Some form of illuminating indicator on the output of the transformer is also worth adding - such as a 240-v. red neon. As a 'luxury item', a 250 v.a.c. FSD moving coil meter on the Variac's O/P is a worthwhile added 'extra' too.
