Dear OM
The circuit to add pilot lamps to the AC/DC 670A is complicated by the problems of isolating the live inner chassis from the earthed outer case. It needs special lamp-holders and these are too close to the frame for safety.
There is no low voltage available, only a series connection with the 110/230 volt supply. It is necessary to add thermistors to protect the lamps . . . . The procedure is not recommended by Eddystone on grounds of safety.

Ok, thanks for the answer. I wonder if I can add an bulb or two in
this set, do I find 12V in there? Or perhaps 110V...... I am using
the set with a converter to 110V, it runs cool then...(sorry for my
bad english...)
