Hi, a linear power supply needs an expensive and heavy transformer and must be well made so that it doesn't get too hot. Even so, the operation is quite uneconomical.
Nowadays, battery operation is offered, charged from the mains by a cheap switching power supply outside the operating hours or by the sun.

I knew a guy who charged batteries on cheap electricity at night and powered them with RIG during the day. That still solar panels were only on Russian satellites and Japanese calculators.
