the receiver doesnt look like a commercial unit, the amplifier maybe

but the request doesnt require that info.

As @Bluejets hinted at, the op is going to need a dual rail PSU to be able to run both those circuits together

This isnt really a problem as there are nice little modules available on ebay etc that take a single rail in and output dual rail supplies

here is a good example ......

The drama comes when trying to combine a " no common" dual or 18v single supply( not very clear in the provided schematics) with a single ended 9v supply.
