FFT of Valve Input

RIAA

This graph shows the equalisation curve of the

channel RIAA input. This compensates for the response of
the pickup cartridge to result in a flat music response.

Valve channel distortion

This graph shows the

harmonic distortion associated with the valve preamp. The
1kHz test tone is shown, together with a strong second
harmonic distortion. This accounts for the ‘musical warmth’
associated with valve circuits.
