- Notes
-
For home construction, almost no wiring. Makes use of the Loewe patents. Plug-in coils to select wave bands.
No reaction is employed, the two-coil holder being used as a coupled tuner. In addition to the use of resistance coupling, high quality reproduction is ensured by anode bend rectification, the first valve operating with a separate HT voltage of 60. The second valve and the power valve are both supplied with HT at 120 volts. The anode resistances have a value of 3 megohms, and the grid leaks 4 megohms.
Price: about £ 9, including accessories (valves, batteries and loudspeaker)
