Ever Ready Sky Casket
I saw this radio in an antique store in Cardiff when on holiday last year, and thought it unusual enough to take a gamble on it. It was in poor shape cosmetically, with the covering frayed at the edges, one knob incorrect, and just generally looking sad. When I removed it from its case I had a horrible feeling that the valves wouldn't be any good, because the HT and LT wires were twisted together. Sure enough, all four valves were bad. I purchased the service data from this site, and found earlier posts about this radio that helped to identify the power supply wire colours. I also asked a couple of questions in the relevant forum, and got some help, for which I am most grateful.
The electrical repair consisted of replacing all of the Hunts capacitors, plus the one electrolytic, and of course all four valves, which I was fortunate to find. I also cleaned the wave change switch. I connected 10 9 volt batteries in series for the HT, connected them to the radio along with a 1.5V LT supply, and it worked. Very pleased! I carried out an alignment, and that side of the job was done. As far as the cosmetics are concerned, I scrubbed the case with a spray cleaner and toothbrush, and it lightened it up considerably. I glued the frayed edges with a white (PVA?) glue. I used Brasso on the metal fittings, and replaced all screws with new brass ones. I removed the speaker from the lid, and then removed the grill cloth from the baffle board. I tried to clean it, but it was stained too badly. it is better than it was, but not perfect. All in all, I don't think it turned out too badly for my first valve portable project. I have attached photos showing the difference in colour before and after cleaning. |

Re: Ever Ready Sky Casket
Well done, Colin. You've done a very good job on that cabinet. These battery valve portables are sensitive and can give very good performance.

Re: Ever Ready Sky Casket
Good effort!
A radio saved, a few hours of fun, and lots of listening pleasure ahead! Agree Phil, the standard 4-valve battery superhet is a good, stable, sensitive circuit. |

Re: Ever Ready Sky Casket
Well done Colin - I have a couple of these in the 'roundtuit' pile, which doesn't seem to be getting any smaller
