Warm tips

1. All outputs work at the same time. The volume/treble/bass are controlled simultaneously.  

2. If the VU meter needle isn't moving noticeably, please turn up the bass and the master volume.

3. 10-second warm-up required; audio delayed during tube activation.

4. The TUBE-T5C with 1PC pluggable NE5532 op-amp, can be upgraded by dual op-amps like 2134/2604/5532/2068/muse02.

5. Default one ECC83 tube, can be directly replaced by PSVANE 12AX7-S and Shuguang 12AX7B / 7025 / 12AX7 etc.

6. High voltage inside, please turn the TUBE-T5C off first before replacing the op-amp and the tube, and avoid dropping anything inside.
