Today has been a nice warm day so I've largely been listening - outdoors - to my Roberts R707. I've retro-fitted it with an internal 12V SLA cell to replace the two standard 6V lantern-batteries; the audio-output stage of a R707 deserves being fed from a really-low-internal-resistance supply if you want to take full advantage of its power and bass-response.

Ditto!
I have several 707's, but they rarely get any use, however, I have removed the battery holder to enable me to fit a 12v 2.3ah SLA battery into one of my more rougher examples.
It certainly lasts for months before needing a charge, and more importantly, can be used as a portable as intended.
