• Anotaciones

• Airzone model "560" is a five-valve receiver, using chassis type "521", which is designed for dual-wave coverage and operating from 200-250 volts A.C. mains. This receiver is housed in a moulded cabinet of the mantel type, and is fitted with four controls - volume, tuning, wave-change (with wave-band indication by dial-scale illumination), and tone (3 positions). The loadspeaker fitted to this receiver is a 6½ inch unit with a field coil resistance of 1,500 ohms. This receiver was introduced during 1937.

  The design of this receiver is quite conventional and circuit analysis should present no particular difficulty. Points to watch are the shunt-fed oscillator feed-back system; the section of the wave-change switch which short-circuits the broadcast oscillator grid coil when the receiver is adjusted for S.W. operation; and the bleed bias system for the type 75 triode section.
