A set of eight tuning forks with plain or threaded shanks providing a complete diatonic scale. Anodised aluminium Frequencies (Hz): 256 (C), 288 (D), 320 (E), 341.3 (F), 384 (G), 426.6 (A), 480 (B) and 512 (C) Arranged in a compartmented Polished wooden case.
Four tuning forks are mounted on a single proper sized resonance box to produce a major chord. Forks have frequencies of C1 256, E 320 Hz, G 384 Hz and C2 512 Hz. When struck together with hammer, the forks will produce the chord of C major. Supplied complete with one hammer.
A heavy steel fork of about 60 vibrations per second is mounted on a heavy cast iron base with provision for horizontal or vertical use. The electromagnet is adjustable so that the amplitude of vibration may be varied between wide limits. Accurate frequency adjustment. Complete with mirror for Lissajou's figures experiments Electromagnet can work on 6Volts DC .
