I can't recall where BubbaFet mentioned finding his working example, plus the exact details weren't revealed if I recall // doesn't matter, this is an open ended problem that should be explored individually - as a result more circuits ideas will crop up ... I can give working hints when I get a chance // for now it's sufficient to say that we can produce the desired result by simply sticking a working circuit in front of a Common-Cathode gain stage (front-end of a tube amp) or any Common-Source jFET gain stage based circuit ... simple enough !
as far as making dough with this idea, turns out this is not my lifetime for making that happen it seems // either I get a straight job and secure some comfort, or gamble my health in exchange for my rewards of discovery - can't have it both ways unless some form of patronage gets set up (paypal?!) ... I was destitute as a math student in university, pacing for weeks to solve a single problem, year after year // same thing with last 20 years playing electronic fantasy // honestly, I much prefer living on this side of the fence, I feel fortunate despite the many hardships along the way ... certainly, I have barely paid rent for years building my Bass preamps and other inventions but let's face it this old jet plane has had its belly rubbed real hard on the ground many times and I'm a little banged up by now (LOL) // sometimes it's not fun, but then again my sense of discovery seems to come out more when I'm not doing too well in the comfort dept. // that's just how it is for me ... I'm into the hunt for what it is, sheer thrill of discovery, and the pleasure of sharing ... but I should say, this Triode transfer emulation stuff turned out to be more than just fancyful academia in action // this is an idea that has a very fun practical side if you're a guitar player ... you'll see what it can do once you start playing with it // myself, I prefer not to look at this as tube amp replacement therapy but rather enhancement type stuff ...
if anyone feels like they could setup a donation plan for me to continue surviving that would be nice, but me and money don't seem to jive in that sense (my marketing skills simply suck too much), plus the way things are going I think I'd be waiting a long time to see any return // it's too dog eat dog anyway once you try getting into all that) ... life is finite and I have no expectation to make money from my discoveries (some of which has been many times plagiarized over and over by one of the stars on this forum) ... ultimately, that's not so important to me, I'm not here for that reason ... one thing I have thought of doing is releasing the MOJO Booster idea in the form of a kit // I'm trying to get that done before I get evicted next month ... we'll see if I can pull it off
without trying to sound too immodest I'll just say this, plugging the MOJO Booster in front of a tube amp leads to a pretty neat synergistic effect, and that is real fun for me // the idea of emulation leading to an additive dynamic push of sorts ... indeed, playing with dynamic compression goes beyond the typical block-mode compressor circuits we all know // not that they (character type circuits) are BAD or anything, for sure they have their place - but this is a little on the newish side ... for one, there is no "trailing" effect via the diode-and-capacitor charge/relaxation combo commonly seen in these types of circuits, as a result it's very natural feeling ... I had one guy race back in the club from his cigarette break after giving me his rig to play a tune on wondering "wtf" I did to get that response ... those little situations make it kinda fun, it's not just a bunch of pretentious blather but real-working stuff ... sonic rocket fuel in a little box ...
tca, I commend and thank you for your (real time) plots // they suggest bone fide class-A Triode circuit action ... I bought a Nano DSO a few months ago and just realized I shoulda got the dual-trace version // with that I plan on demonstrating the idea in action in terms of a time-varying transfer profile in a somewhat similar way to how these guys did their testing of non-linear circuit transfer:
http://www2.hsu-hh.de/ant/dafx2002/papers/DAFX02_Moeller_Gromowski_Zoelzer_measurement_nonlinear.pdfin essence this type of analysis would constitute a substantial departure from taking the (ubiquitous) Steady-State analysis approach we have all been taught in school // I could go into details why this is so, but that's a long story ... in a nutshell this is a new approach to characterizing Transient response activity in signal processing circuitry // it took many years after leaving school for me to ponder just exactly why all they teach in school is small-signal (System) theory ... I'm parked outside a cafe and it's getting cold // I gotta cut this short, but when I get a chance we can get into the nitty-gritty of all that other stuff ...
cheers // and thanks for following me down this rabbit hole
