HiFi Tube Pre-amp: Analog Scope Testing

This is the start of the line stage pre-amplifier shootout!

We have 3 different China clone pre-amps, 2 were prebuilt, one I built with quality parts from a ebay board. We look today at basic analog waveforms and all seem to be capable performers at this point. The jury is still out on distortion, noise and sonic quality. Here is a link to some info about my build, this info could change as we play around with these.

This is a project I am excited about as this is something a lot of folks have asked about: a tube pre-amplifier. My build is a clone of a Conrad Johnson pre-amp that uses four 12AX7 tubes. Zero-zone sells this already built for $260ish, but I wanted to build this myself using known quality components and my own layout.

I plan to cover the other pre-amps tested in more detail in future videos.
