Good morning Fernando,
The two oscillators (NTO & PCO) have had both the saw wave core
along with their triangle and sine wave output waveforms modified with
newly selected audiophile grade ICs along with special frequency
compensation networks added and adjusted for the best sound I have
ever experienced in a music oscilator. Evenly focued throughout the
entire audio spectra with extremly smooth detailed harmonic definition.
A [PS2a] power supply is also available, if you require one.
Thanks,
Harry
