I like it it just to come with a power cord

Using this somehow makes the audio quieter. With no amp i have to set the hifi volume to 30 to hear audio, with this it needs to be at 36 and has a horrible buzz.

Others have also mentioned that you have to source your own power cable. They also say no instructions. If you know what you are doing the PCB has screen printing that explains most of what you need. Does not specify power need on board. I’m using a spare 12V 3A adapter I already had lying around. As for audio quality it seems fine to me. Seems no different than the non-tube amp I use on another of my systems.

All I can say is wow. Soft mellow tones with hard striking drums. Love it.

This device is not a phono preamp and will still require a phono preamp to function. It does add warmth to any line-level signal sent through it, but don't buy this thinking you're getting a one and done preamp as they advertise. Maybe a miscommunication or bad translation, I'll give them the benefit of the doubt, but the fact they include no manual listing input /output impedence levels, no power supply included so I'm just guessing what will work and hope the board doesn't fry.... If anything this package is cheaper than buying the parts separately to build your own tube preamp

Great device it has worked perfectly

The tubes came loose in the box . it has no power supply, had to seat tubes legs bend should of come installed and tested . i'm not sure i seated the tubes correctly . i used my 9 volt guitar peddle power supply not sure it has enough power. could be me . nice looking item. i'll keep it look at it.

Just like the title says. How do I plug it in? What do I plug it in with? What do the three switch positions do? I found "IN" and "OUT" behind two sets of red/white RCA jacks and nothing else. No manual. No link to a manual. No diagram.
