The design I referenced does give approximate sine waves rather than square waves. The modern approach to this would be digital waveform synthesis and a simple DAC. Possibly as simple as a few resistors. Then a power amp as before.
For most purposes there's not much point in referencing the output to the input frequency. A crystal is more than good enough for most purposes.
