Many thanks to SWLing Post contributor, Rolf, who writes:
I have a Abbree AR-F8 portable.
It had a small problem: the volume would not get to zero, so you hear still hear noise if
the volume knob was on low/zero.
I opened the radio and found a solution.
There was a 100R resistor to ground. Now I have that made to zero R.
After the mod I can now get low/zero volume when I turn the volume knob.
Thank you for sharing this modification, Rolf.
As with any mod, readers should note that you might void the manufacturer’s warranty and/or cause other issues with your radio if not completed properly.
