audio signal went through two switches, a relay, long board traces, around the power transformer, and then to the rca jacks. this was all bypassed, and instead cat teflon twisted pair (one wire grounded at one end for shield) was used to go direct from the op-amp output, through -ohm resistor, to the fixed
lastly, you can add a k or thereabouts resistor from - rail to output which will bias the op-amp into class a operation. if the tuner has both fixed and variable outputs, you can do the wiring mods in such a way as to be able to still use the variable output with muting, and use this for tuning stations...
