How to Diagnose Power Supply Failure?
- The following situations may cause this issue
- Case 1: The LED on the power supply does not light up; Case 2: Amp/Preamp does not turn on; Case 3: When plugged into the Amp, both light on the amp & power supply start blinking; Case 4: Amp/Preamp make noise; Case 5: Sound shuts off by itself
- Possible solution
- Check if the power supply is illuminated when plugged into AC by itself.
Plug power supply into a different socket.
Test the adapter with a meter.
Try a different power supply (within a range of DC input).
Test the included power supply on other electrical equipment.

Customers said this amplifier works well with good build quality and solid performance. The enclosure is well-made and packaging arrives safely. Some noted minor crackling when adjusting volume, and radio enthusiasts reported interference from the switching power supply between 27-30 MHz.
I bought this amplifier at first but later got a new one to suit my needs, but this worked well for when I had it

The amplifier works as expected, with no audible noise apart from a slight crackling when adjusting the volume knob

Package arrived int time and undamaged.
Amplifier looks well made in good enclosure and works well.
Only problem I have, as a Radio Amateur, call sign 5B4AZ, is powerful noise interference between 27 and 30 MHz that is apparently produced by the switching power supply. This problem existed with a similar amplifier of another make I had before the Fosi. Switching supplies and amplifiers don't agree with sensitive radio receivers but seem unavoidable. :-(
