Sir Gatesheadkeith . . . . .
That's quite a variance in your troubleshooting trip and changing from a toroid transformer to a dual voltage controlled low noise amplifier chip.
How low noise is it ? . .well if you had it in your audio processing loop, you would be able to hear the sound of a mouse peeing on a cotton ball .
The parent developer of that PA381 chip is On Chip Systems.
But it has been second sourced in its supply at Curtis Electro Music Specialties.
Researching for a supplier ends up at the " Alibaba" far east sources.
You are just going to have to seek out the supplier that will sell you just one chip and at the best price .
Thaaaaaatsit . . .
