  • Notes

  • The B-Less One-der

    Following the remarkable success of the "HIKERS ONE", our Technical Department have pleasure in now submitting particulars of the "B" Less One. This set can actually be used without a "B" battery, and excellent results have been obtained with just a 2-volt "A" battery. Particulars of the battery connections, etc., are given later in this article. It must be pointed out, however, that with a "B" battery of even 1½ to 3 voÍts much better results will be obtained.

    This is a most interesting circuit as the "B" voltage can be varied from nil to 45 volts. This little receiver is rather unusual in that it utilises the 1E7G valve, which is a twin pentode (Detector and Audio Amplifier) and can be successfully operated over quite long distances without any "B" potential. Naturally greater volume and more sensitivity are to be had when a "B" voltage from only 1½ volts to the usual 45 volts is applied. 

    Complete kit without valve, speaker, headphones or batteries 30/-.
