The oscillator chassis contains the two pitch oscillators and the expression (volume) oscillator.
The Power Supply/Audio Amplifier chassis provides power to the electronics and contains a 10 watt audio amplifier
which will drive a standard 8-Ohm speaker. The wired chassis set is hand crafted using new modern electronic components.
Some parts which are no longer in production (i.e. vacuum tubes) will be new old stock or used but test good and are fully
functional. The wired chassis set is supplied with all tubes. Included also but not shown are the pitch and expression
aerial coils. The chassis are supplied pre-aligned and "burned in" under power for seven days in our test bed and may require
only minimal alignment after mounting in your cabinet.
