JC Maillet, posted Oct22/2020 … A quick look at any good circuit theory book and you generally find jFET device equations written in terms of the process-dependent constants Vgs(off) and Idss. Together,Vgs(off) and Idss pin down the CHARACTERISTIC relationships which …

pushing sleep late one night, I randomly started drawing out a sine wave and reflected on a visual representation of the usual frequency doubling transform known as “full-wave rectification” … I bemusedly wondered if there could be another way of …

While searching for a non-code based (AVR) way of doing 3-phase speed control on the WAYNE Choratone concept I found a way to discretizing the phase rotation so that an easier way of balancing the Lattice outputs becomes possible. Instead …

viva Analog “1176x-tended” Limiting Amplifier my take on the celebrated giant … CONTROLS: PRE // Input scaling (affects RATIO and THRESHOLD range) POST // Output (overall) gain THRS // minimum Threshold (high sensitivity) at full rotation RATE // maximum Ratio …
Bagging a new Phasor circuit … To recap, all monaural time-based effects – which includes Delays, Phasors, Chorus circuits and Flangers – all tend to follow a similar overall structure comprising of three main parts: (i) a signal path that …

Introducing: The ATAK-60 “Analogue Tube Amp Killer” // 60 watt version A culmination of the work I started in 1994, with a first official publication of my 12ax7 modeling and simulation plots in 1998. Maillet-GlassAudio98 PDF These plots provide an …
auto-bias circuitry ?! … hmmm, is that reliably possible …?! I’m always curious to see what kind of approach these rocket engineers will take to complicate the basic tube amp design … as if the Traynor auto-bias fiasco wasn’t enough …
The schematics I was able to find online were scanned at a very low resolution … I tried my best to improve their legibility … what I have is posted here below, … the amp had a few issues that …
