Summary
| Description |
English:
The variable condensator C1 in the LC circuit L1, C1 selects the frequency. Potentiometer R2 controls the regeneration. The tickler coil L2 has inductive coupling to L1. C2, R1, D1 and the transistor Q1 internal base to emitter diode are the grid leak detector. The diode D1 allows a larger voltage at R1 before clipping happens. C3 is a short circuit for radio frequency. The headphone has high impedance.
