EQ dreams

Since the EQ sounds so much better on the custom amplifier than it did on the HTR-5230, decided the long term should include a bigger front panel with a knob for the bass & enough room for a treble knob. There's enough room to fit 2 more pots by merely making a slightly wider front panel & mounting the pots diagonally. Also, the order from left to right needs to be power switch, LED, EQ, volume. This is the international front panel standard.

The HTR-5230 had 2 25k pots for the EQ & a 100k pot for balance. The 100k pot was specifically for balance & couldn't be reworked as a resistor divider.

The treble is always going to be at full. Sometimes the bass should be at full & sometimes it shouldn't. This was realized by Japanese decades ago, with their famous bass boost knobs. Helas, the age of bass boost is long gone. Steve Jobless didn't include it on the ipods & everyone has since dropped it. Not sure why this is.

A load switch to disable the amplifier until after the CS4227 initializes is on the plan. The speakers also need a way to easily pitch up & down.
