FAQ
1. Can Trends PA-10 Tube Headphone/Pre amplifier be the Phono Amplifier ?
No. Trends PA-10 Tube Headphone/Pre amplifier does not support RIAA.
2. What are the difference between CD Input and Phono Input
The CD is normal input. The Phono input with higher gain is provided for small output phono amplifier or PC/Mac/iPod.
For example:
CD Input: Standard gain = 3 x
Phone Input: Hi gain = 20 x
3. It is very loud, boom with flabby bass when I turn on Trends PA-10. Why ?
It is normal that the vacuum tube have to warm up for several minutes to the stable condition. The temperature is also a factor for the bias voltage.
4. I once accidentally turned on the Trends TA-10 T-amp before I turned on the Trends PA-10 Pre-amp and the tube kept blinking with an intermittent popping sound. Any explanation for that?
We suggest that you turn on the Trends PA-10 Pre-amp firstly. For example:

5. How can I change another vacuum tube for Trends PA-10 Tube Headphone/Pre amplifier?
Trends PA-10 Tube Headphone/Pre Amplifier supports two major tube series: (1) 6DJ8, 6922, 6N11, 6H23n, ECC88, E88CC, etc…, and (2) 12AU7, 5963, 5814, ECC82, etc… If you change the tube within the same series, it needs to re-tune the DC bias voltages ONLY. If you change the tube from another series, it needs both to re-tune the DC bias voltages and re-set the jumpers. Otherwise, the tube may be burnt out.
