No Serial Number
GEC Transistor Radio This is apparently electrically similar
to model G820 but it has no markings to indicate model or serial
number. [On this model the sockets are mounted on the sides of the case
rather than the back, the aerials are on the right hand side and the
tuning control knob is on the front of the set]. I think it might be a
This is an AM/FM radio receiver employing ten transistors and four diodes. Press-button selection of a total of eight wavebands is featured, including band-spread facilities on a section of the medium waveband and on the 13 and 31metre Short Waves broadcast bands. The receiver is housed in a wooden case measuring 13in by 8in by 3in deep and employs a 6in by 4in loudspeaker to handle the 800 mW of audio power available. An edge-mounted meter provides tuning indication and warns of falling battery voltage. Waveband ranges are: 1,1O5-2,OOOm (LW) 191-570m. (MW); 178-211m (band spread MW); 29-95m (SW); 31m band (band spread SW); 13-42m (SW); 13m band (band spread S.W.2) and 87-108 Hz (FM). An internal ferrite rod aerial provides reception on MW, LW, band spread MW, SW1 and band spread SW2. Separate telescopic aerials are provided for FM reception and SW reception. Sockets are provided for feeding a tape recorder and for the connection of an external loudspeaker, the internal loudspeaker being muted on insertion of the plug. A socket is also provided for the connection of an external car-type aerial. Transistors [as indicated in 'Trader' service sheet 1796 for the G820]: AF178,AF115,AF115,AF116,AF116,OC71,AC127,OC81D,OC81,AC127. It is powered by a 9V battery type PP9 (or equivalent). UK 1967
I was lucky to get this radio as part of a job lot on Ebay as nobody else seemed to want them. It worked fine on all wavebands though it would suddenly stop working, all wavebands being affected. It had been opened and was loose in the case and one of the telescopic aerials was missing. I soon discovered that upon dying the set could be brought back to life by tapping one of the AF115 transistors. I cut the screen lead on this transistor and all seemed to be well but for good measure did the same for the one in the VHF tuning section. The radio is now working well though the band spread button tends to stick in the depressed position.
