Europa A-280

The Halcyon Europa 5-valve transportable is the result of months of scientific investigation and now satisfies the most exacting demands of the wireless enthusiast, whilst ease and simplicity of control are appreciated by the merest novice.

The circuit is based upon the famous superhet coils, which proved such a success in the W. James' Super 60 receiver, recently described in this publication. There is but a single tuning control, no reaction, and neither outdoor nor indoor aerials nor earth are necessary.

The selectivity of the Halcyon " Europa " is knife-edged. The National and Regional stations can easily be tuned out in one degree. Five-valve band-pass supersonic Heterodyne receiver, embodying detector and oscillator valve, two screened-grid intermediate frequency amplifying valves, detector, and pentode output valves. Single dial ganged condensers. Celestion speaker. Scale in metres.

Plugs are provided for gramophone pick-up.

Complete with B.R.V.M.A. valves, H.T. and L.T. batteries, and all accessories, and including royalties 22 guineas.

Also available in a mains-powered version.
