Panatrope Junior De Luxe

There are five models from 41 guineas upwards. The Junior De Luxe (illustrated) sells at £80. and is essentially an electrically reproducing gramophone, with no radio frequency equipment included.

If a separate wireless detector and aerial are available there is, however, provision by means of a plug and jack for broadcast reproduction. B.T.H. pickups are used in all models and high-resistance potentiometers are used throughout as volume controls.
The Panatrope under review has a mechanical motor, but for £8 extra an electrically driven motor can be obtained.
The amplifier contains three valves transformer-coupled as two stages; a B7 valve is followed by two B12s in parallel. The filaments are heated by raw AC, resulting in an almost imperceptible hum, whilst the anodes of the two parallel valves are fed at 240 volts from two RH1 rectifying valves. The loudspeaker is a moving coil Rice-Kellogg with a mains-driven field. Comprehensive screening of the rectifier equipment has been affected to prevent magnetic coupling.

Besides a dual turntable cinema equipment, there is an elaborate model at £135 entirely mains-operated with one B7 valve and three B12 valves in parallel with 450 volts H.T. The volume from this gramophone when demonstrated was adequate for dance halls and public meetings.
