Graphic EQ of 5 tubes per channel for frequency adjustment, one frequency per one triode part, so two frequencies per tube, one tube as a differential pair and half of one as a cathode follower.
Frequencies will be 32Hz, 64Hz, 125Hz, 250Hz, 500Hz, 1KHz, 2KHz, 4KHz, 8KHz, & 16KHz.
The unit will consist of two mono blocks pcb's, so I could build a mono EQ, one power supply pcb and two frequency adjuster pcb's, which by the way ended up being a 4 layer pcb!, one for each mono block. Adjustment will be via rotary potentiometers. Attached is a front panel design.
