Tapped Aerial Tuning Unit.
Tapped tuning coil (10 taps) with reaction variocoupler, five steps switchable.The tuner under review is a product of the British General Manufacturing Co., Ltd., and although this is not a new accessory it incorporates a number of novel features well worthy of mention.
The general arrangement is a tapped single-layer coil wound on a 3” diameter former with an internal cylindrical reaction coil at one end. At the other end is a totally enclosed 10-point switch. The control spindles for the reaction coil and switch extend beyond an oval-shaped front plate cleanly moulded from Bakelite and terminating in moulded knobs 1½” in diameter.Both sides of the front plate carry embossed markings arranged so that the tuner can be mounted either horizontally or vertically. Four terminals are provided, one each for aerial and earth and two for the reaction coil. Full instructions for fixing are given on a leaflet enclosed in the carton, and to facilitate marking off the correct distance between the two fixing holes a drilling template has been printed on one side of the box.
The unit tunes front 250 to 2,000 metres with a 0.0005 mfd variable condenser in parallel and connected to a standard PMG receiving aerial.
The price is 18s. 6d.
