Sounds like you have a sensible wife interested in your sanity and side hustle. Were that we were all so blessed.I thought about it, but you're exactly right, Neptunium would have to go into a bigger box if I were to do it C2C style. I could probably fit it into a 1590BB so it would be a similar setup to Venus Z, so it would be smaller than Nobelium, but not by much.
They're not wildly different, but they're not not exactly the same circuit either.
For things like this I really like talking to my wife, because she's not an engineer or a musician, so I can get unbiased opinions from someone who is not completely removed from the situation but definitely less emotionally involved than me. She asked how many other projects I have in development, and I told her. She asked how many of them are similar in operation (D.I., preamp) and I told her. She then asked how many people have expressed interest in another run, and I told her. She said she thinks I should do it, but not until I've cleared a couple things off my plate. So we agreed I should finish up a couple things and then revisit the discussion. And I felt pretty good about that conversation. So I guess it's turning from a "no" into a "maybe"?
Not that I have any complaints. I constantly remind myself how lucky I am there, much better than I deserve although I do my best.
