Figure 11.2 Frequency response of two band tone control with pentode amplifier. Figure 11.2 is almost identical to figure 8.2 with two notable exceptions. The tone flat curve is indistinguishable from 0 dB. And the high end does not roll off but continues out to 100 kHz as follows. Maximum cut, 10 kHz, minus 9.5 dB, 100 kHz, minus 14.2 dB. Half cut, 10 kHz, minus4.5, 100 kHz, minus 5, Tone flat, zero dB all the way across. Half boost, 10 kHz, plus 4.5, 100 kHz, plus 5. Max boost, 10 kHz, 9.5, 100 kHz, plus 14 dB.
