Now that we have the Sound Transformer looking a little more presentable, here is a short (one minute) video of some jazz playing through the system.
This is from a monaural vinyl LP that I have here. The sound is really quite good. It is not necessary to turn up the volume to hear every instrument. However, it is possible to raise the volume considerably without any increase in distortion. I tried this while wearing Howard Leight T3 hearing protectors.
Here is some Country Music. The video is a little less than 2 1/2 minutes long.
This is from another vinyl LP that I have here. It is remarkable how faithfully some of these monaural LP records were recorded.
