Warm tips
1. The bias and gain of two 6E2 tubes are set well before shipping, please pay attention to the R/L channel markings on the tubes, don't insert them wrongly during installation.
2. 3.5mm headphone jack with priority, please make sure the headphone has been disconnected if you want LINE output.
3. If the ANT is not connected to an antenna, LINE OUT can also be connected to an audio cable or headphones as an antenna.
4. It's suggested the 6E2 tubes be turned off when displaying time for a long period.
5. When AUX input is plugged, only clock/sound level modes can work. In Radio mode, the VFD can only display radio frequency.
