My grandfather passed away nearly a year ago. I was home for Christmas and my grandmother asked me to go through his workshop and take anything I wanted. I found 2 boxes of tubes that he must have pulled from a Baldwin electric organ. I've got a whole pile of 12AX7s and 12AU7s, a few 6L6s, and some others. I haven't built any tube gear. Any recommendations on starter projects? Maybe a phono preamp (MM) or headphone amp?
