inconvenient design mistake

Two separate volume knobs for L and R are very inconvenient to use as volume control.

They are for fixed gain adjustment to improve total system S/N (or to have volume knob on pre-amp at the angle range with small channel error), and for fixed L/R balance control.

Once one touches the big volume control knobs during cleaning etc., one needs to re-adjust the L/R balance with test signal and multi-meter. The pair of big separate continuous knobs is a design mistake.

The knobs should be small and recessed if it is continuous adjustment type, or the attenuator should be stepped attenuator. If the designer intended everyday volume control, it should be a single stereo knob on the front panel.
