Nobsound E6 Direct Heated Valve Tube Preamp Class A Stereo Audio Pre-Amplifier Home Desk Stereo Pre-Amp with Volume Control

Bought one last Jan,`23 .For use as a pre-amp,to drive a sub-woofer,which it does 2 well!.Well, I have a similar problem so, went with what I know.Build Quality is fine,these valve/tubes, were used before WW2,and still around,wont see a i9/R9 in 80+years,they be gone.

This amp was intended to enrich the tone of my PC soundcard, used as a pre-amp. There is one fairly important drawback in my particular case, the valves are easily affected by ambient sound and vibration. They are really sensitive and any nearby movement sets them off with the result that there is always a fairly high pitched overtone coming through the speakers. The amp would probably be great at home but I can't use it in my work environment, looks good but can't quite deliver on the sound due to the environmental set up here.

Very happy with this, it has added a far richer sound when playing vinyl.

I bought this to use as a preamp to feed a power amp. Very good value for money and sounds good as well. Two small niggles, why are they not supplied in manufacture's box and the Russian valve equivalent stated is not the right one.

Item never worked,made a crackling sound,then no volume,sent back promptly.
