Operating tubes at low plate voltages exaggerates natural warming distortions … Fig. 3 shows a typical triode vacuum tube.  Because of the Edison Effect, heat from the filament causes free electrons to boil off of an oxide coating on the cathode.  A positive voltage on the plate attracts the electrons and the moving electrons produce…

Dynamic Mics It is fairly obvious that the circuit shown above adapts the TMP’s XLR input to the increasingly popular 1/4″ balanced lines, but there is more here than immediately meets the eye.  Notice that the sleeve of a MONO phone plug grounds the ring of the STEREO jack and consequently the inverting input of…

In the golden age of analog sound every link in the chain introduced warming distortions … If you’ve done any reading about tube amps you’ve probably noticed that much of the legendary “warmth” is attributed to the differences in the way tubes and transistors respond to overload signals.  I believe this is true, as far…
