LM 3886 18v at output

I will soon build two amplifier channels using this chip when my order arrives home. The PCBs have been made quite neatly using the acetone toner transfer method and a solution of hydrogen peroxide plus muriatic acid as etchant. The remaining step is to carefully inspect all the tracks for minute shorts with a magnefying glass. After that, I will check that the PCBs comform with the chip's pinouts. Misplaced schematics in the internet are not an impossibility.
