Electric 42

This set is a 4-valve A.C. mains transportable and is fitted in a highly polished mahogany vertical type cabinet measuring about 20 ins. high, 10½ ins. deep and 19 ins. wide at the bottom, tapering to 18 ins. at the top. A turntable is fitted.

In front, the output and earth terminals are mounted on a vertical S design, are two hinged doors, which can be locked, and which enclose the sunk mahoganite control panel.

Inside these doors are two station logs, containing most of the usual British and Continental stations normally received, with accurate calibrations.
The controls comprise two slow-motion condensers for aerial and H.F. tuning, fitted with nickelled pointers, the scales being engraved on the panel. The volume control is a differential reaction condenser, while there is also a 3-way switch giving "off," "long" and "short" positions.
At the back of the set, there is a hinged door, provided with a lock, which gives access to the inside. At the bottom right-hand side this door is cut away, and behind it is a panel containing the plug and sockets for the mains connection, sockets for an external aerial and earth connection if desired, and jacks for an external speaker and gramophone pick-up.
On opening the back, the small panel will be seen to contain in addition provision for adjusting the set for mains voltages of 110, 200, 220, or 240 V. Inside the cabinet there is a platform carrying the receiving valves, with the components and wiring fixed to the platform, either above or below, while at the base of the set is the loudspeaker and rectifying and smoothing equipment, closed in by a 3-ply panel. A hole is cut in this to give
access to the Mullard DW2 rectifying valve for the H.T. supply, and also to enable the loudspeaker movement to be adjusted. The speaker, by the way, is an Amplion B.A.2 unit and chassis.
Mounted on the left of the horizontal platform is a screening box, with a removable cover, containing the Mazda SG/AC screened grid H.F. valve and the Mullard 354 V detector and their associated wiring. Outside the box, towards the right of the platform, are Mullard 164V and 104V valves, in the first L.F. and output positions respectively.
The circuit incorporates the tuned screened grid H.F. stage, grid leak detector, and two transformer coupled L.F. stages.
The set, complete, sells at 42 guineas.

NB: Advertised as an AC/DC set however the technical writeup states AC only.
