Some time ago my sister gave me a junk Hanimex combined B/W TV and AM/FM radio portable 12/240 volt set.
Back then in the 1960's this must have been the last word in circuitry and a consumer device.
Now the VHF TV channels have gone and only the AM/FM part was useable.
For fun I worked out how to patch a UHF receiver to it.
I only made this up to run from 240AC volt, the Hanimex from its own 240 volt plug and the STB from its own 240 v AC plug pack.
If I tried harder I could get the STB to run from an internal DC power supply in the Hanimex when used on 12 volt DC supplies.
Mains is good enough for this exercise.

This of course is a technical exercise, but I do not see why the same exercise can not be applied to any valve or transistor B/W or colour TV.
Anything to make them useful again! The little set top box or "Satellite Receiver" same as I integrated into my 3" valve set could be hidden anywhere in a big box 1960's onward TV set. A remote control then makes operation easy, or, you can use the buttons on the front of the tuner as I did in the 3" set.
