"All-Electric Radioplayer"
Three-valve (+ rectifier) AC TRF receiver. Mottled brown Bakelite cabinet and back panel. Oxidised bronze grille with leaves and red loudspeaker cloth, cadmium-plated bent iron frame chassis. The radio, designed by ir. Louis Kalff, is a nice example of Art Deco design. The 2634 was the first Philips radio with an integrated loudspeaker (type 2034, type 2044 in the first models). The chassis has a date stamp of July 16th, 1931.
The DC version is the 2637.
The volume control knob and the wave band selection switch are situated at the left hand side of the cabinet; reaction control, tuning and fine tuning at the right hand side. Radios using a B443 as output pentode have a switch that can be used to disconnect the internal loudspeaker.
The first newspaper advertisements appeared on February 27th, 1931; the radio was introduced at the Jaarbeurs Fair in Utrecht, that was held from March 10th until March 19th, 1931. Magazine Radio Expres described the radio as "very modern and bold". The original price was f 257,50. 
The two circuits are tuned simultaneously using two mica condensers on one shaft. Philips used this system for the first time in this radio. A small knob is used to adjust the first circuit. Wave lengths: 200-450m, 400-950m and 900-2100m.
