Philips 2511

 This radio, made in Holland in 1928 or1929, looks more military in nature than domestic. It measures about 20" by 11" x 9" and weighs more than 45lbs (22kgm) being constructed from a steel frame infilled with bakelite fastened by copper rivets. This material was known under the trade-name "Arbolite"

There is a complex chassis carrying five valves, including a pair of screened grid types with the RF sections enclosed by steel covers; one over the valves and the other over the tuning condenser.

At the left end is a heavy mains transformer, the rectifier valve and the audio output valve.

The case is embellished with copper decorative features and includes a lockable lid.

A useful feature is a pair of metal strips on the underside of the lid for holding papers carrying station logs. These were necessary in the days before dials marked with transmitter names so that users could readily tune to the program of their choice.

The tuning knob is at one end of the case and the reaction control at the other. The ornate dial escutcheon extends to include the keyhole for the lock and a wavechange switch.

There's a safety feature, to prevent electrocution of the user, consisting of a series of levers connecting the right hand end of the lid to a mains on/off switch, although in this example it has been disconnected.

 

 

 

 

 

 

 Overall the set is in reasonable condition for its 75 years and poses the question as to how far one takes refurbishment. Clearly there is a multitude of scratches to the paint finish of the black-painted frame, together with dents and areas of missing paint. It would certainly look a lot better if the old paint was stripped off, dents filled, and repainted in shiny black hammerite for example.

Restoring operation may not be too difficult as good quality components have been used in the construction.

The last picture shows the interior with the valve screen removed.

When first sold this set was extremely expensive, at nearly £40 (excluding a loudspeaker), being about twice the price of ordinary sets. When one considers that a small car was around £100 in 1930, in modern terms the set would cost about £3,000.
