I was going to helpfully suggest that you gaffa tape a soldering iron inside the radio and simply turn this on when you wanted to use the radio ;)

Glad you got it sorted!

There's another dodgy receiving DNT on ebay that you have to bang the top of sometimes for it to work properly. These are obviously quality radios ;)

When working they are very good but reliability is crap.
I had to resolder so many dry joints on mine and the boards are very fragile.

I've got a nice, boxed supertuned one, but I daren't now ever power it up again in case it blows up! I'll stick to my 100% reliable Amstrads and Fidelity 1000's :)

Yeah, I had a B40 homebase one a few years back with the pop-out feet. It had its box too which was a rarity but I flogged it as I don't really do homebase radios.
