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.
