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, dont insert them wrongly during installation.
2. 3.5mm headphone jack with priority, please make sure the headphone has been disconnected if you want RCA output.
3. Pluggable tube socket design, convenient to be replaced by 6K4, EF93, 6BA6, W727 etc. to enjoy tube sound of different styles.
4. T9 is a preamp not a power amplifier, needed to work with amplifiers or active speakers.
