Abstract

1330507 Transistor oscillators WURLITZER CO 16 Oct 1970 [20 Oct 1969] 49327/70 Heading H3T [Also in Division G5] An r.f. oscillator for use in a musical instrument comprises a transistor having an inductor 134 as emitter load and a feedback connection via capacitor 144. Diodes 148, 150 permit higher peak-to-peak r.f. voltages to be developed.
