AMI's 15-watt Oahu Guitar amp, top view

As simple as can be; two channels with two inputs each, channel one with regular input and high pass input.  The cathode of the 12AX7 is grounded and the bias is generated via the start up current. Channel two uses the 2nd half of the 12AX7 that is cathode biased with a bypass cap, a simple tone control in front of the 12AX7 phase splitter that drives either a pair of EL84 or 6V6 power tubes.
