Indeed. Our radiogram was made c1949 by the Seymour Radio Company,
Arbroath, Angus. It had a mains transformer. I re-cased it when I
was 15, and discovered (the hard way!) that even so the chassis could
be live depending on how it was plugged in. First thing I did was fit
a new colour coded flex.


You mean it used a transformer for the heaters but mains derived HT? That
was pretty unusual with radios, IMHO. Meant it was AC only too. Most
cheaper radios were universal - and some used the mains lead as a dropper
too. Nasty things. ;-)
