NOTES |
![]() Also in the sheilded is a H.F. power output valve, the Mullard QQV02-6, driven directly by the DET22. The unit includes a crystal calibrator circuit. A portion of the main output is fed into a 5MHz crystal oscillator. Presumably the calibration oscillator generates a lot of harmonics as these harmonics mix with the main signal producing a beat frequency, the audio component of which is amplified using the one and only transistor and fed to a set of headphones. ![]() |
