Hi Ben, sorry to hear that your new stereo amplifier is already damaged! I am not sure which setup you are looking to use and saying that for my home made PEMF device, I purchased the below devices and hooked up my coil to it. The PWM module will not give you 7.83Hz either 7Hz or 8 Hz up to 1KHz, so not sure if it would be good enough for your tests:
AC 110V/220V to DC 12V 24V 48V 60V 20-100A 1200W Switching Power Supply Adapter
LCD Display Adjustable PWM Pulse Signal Generator Frequency Duty Cycle Module
