As far as I can make out quite a few variants of this fine globe came out from 1960 to around 1966. The black base is made from Bakelite and globe from plastic but most of the unseen inside is anodised steel parts made with a high degree of manufacturing costs, no short cuts. The base detaches with one wire still attached for the telescopic aerial for easy fixing of the 6 x 1.5 volt 'AA' batteries providing 9 volts supply to the 8 transistors for the short wave version and 6 transistors for the medium wave only version. The silver cap at the front allows you to pull out the SW aerial and swivel in all direction. There is a headphone socket and a 9 volt power adaptor socket at rear.
the repair
These are advertised for sale at anything from £50 to £200, globes are 'in' at the moment with home fashion designers. So I have been waiting quite a while for one to turn up at a reasonable cost.
This one had it's fair share of problems that I will explain.
The base cover is held by two chromed screws underneath, that relieved rusted battery clips that originally were held by pot rivets, I removed the aluminium rotted rivets and fitted two bolts after cleaning the corrosion of the springs etc., you may decide to fit a PP3 battery but this needs extra space and all the battery terminals will need to be removed and there are many. After fixing the battery box it was still dead, so I checked the on-off switch by a resistance check across the terminals, should get about 2k ohms switched on and o/c in off positions, this checked good.

I then connected a small battery across the headphone socket to see if the loudspeaker was working, no response, so I need to look inside for a doggy speaker or wiring.
One screw in base, 3 screws holding two halves of the globe together and 5 more under the tuning knob. With all these removed the ball opens and top removes. I found the speaker open circuit and removed that and fitted two small boxed speakers I retrieved from a computer monitor, wired them in series, giving me 12 ohms, the original was 8 ohms. Sometimes using what is to hand is more economical than paying perhaps £5 for speaker and £3 post for a new on on-line.

After fitting speaker I found that the tuning was very crackly in some parts of the band, holding the tuner veins with a white card behind I checked to see where the capacitor was shorting out, quite difficult as is you move the plates too much you will damage them, but with time I re-aligned them so the crackles were a thing of the past. So after repairing the battery box, speaker and tuning capacitor the old gal worked again to survive for many more years - we hope!
