Hello, I have some NOS 12AX7 tubes with me and want to learn and have some fun from these tubes. My concern is that I'm quite new for tube gears. Building a simple preamp would be the easiest way to begin. So I'm looking for some DIY 12AX7 preamplifier projects. I prefer some simple projects that I can do hard-wire. Thank you in advance.
