MP566 Tube microphone preamplifier / GND Pin
« on: April 01, 2021, 05:55:36 PM »
So I am trying to go through the testing document, but the first step says to check for resistance between the GND pin and the V+ / V- pins.
The issue is that I am not seeing a ground test pin. I count 8 pins but none of them are GND. Is there something I’m missing here?
Thanks
