I’m excited to share this one with y’all:) I’ve got a new mic preamp design that I’ve built into this old photometer called the “Densichron!” It turns out this thing already had a mic preamp’s tube lineup: 6j7, 6sn7 (x2) and 6ax5 tube rectifier, as well as a couple cool “mic pre” features baked in like the stepped attenuator and the “insert” point on the back. I kept the best features and added my own favorites like a high pass filter, hi-z input and output, 600 ohm balanced line level XLR output with pad switch, mic input transformer with input pad and phase switch. It’s got a big clean sound but can also be driven into saturation with the output pad engaged. I was also able to re-purpose the big meter as a volume indicator too which is a lot of fun.
