FM Pye Westminster had this issue even with the standard miccrophone.
Usual trick was to add more emitter decoupling to first mic amp transistor.

In this case it has already been said it is an opamp. There is no harm boosting that 3-6dB as any excess when using the stock microphone can be taken out using the mic.drive control.
