I made an Elegant 7 for my mother-in-law. I still have it. I modified
the mains power supply so it would also trickle-charge the 9V
(non-rechargeable) battery (which works - provided you start with a new
battery, don't let it discharge too much, and don't over-do the charging
current). I remember it being not the most sensitive of radios, and
unusually noisy. [I think that some the cheap multi-layer capacitors of
the time were bad for that.] Must dig it out, see if it still works, and
maybe fix the 43 year-old noise problem.


I have a 'Good Companion' built using my first week's wages in 1962. Still
works as well as ever - ie not that sensitive. Micro alloy transistors and
transfilters. The ad men were alive and well even then...
