any V1 cathode bypass would count as a "signal path" C if you're obsessing over Cap quality   discrete diode bridges may be fast recovery - nowadays Schottky are available at tube B+ voltages - Schottky shouldn't need...

the Sound Science forum is the place to debate validity of listening protocols - I simply point out that there are reasons the Scientific/Engineering communities only respect Blinded tests of "audibility", with controls for level...

the engineering numbers make it hard to believe in bypassing audio signal coupling electros with few % film/mica/PIO, whatever FOTM   bipolar - full depth oxide on both foils is "best" on measured distortion for...

when you build your own line powered supply you are stepping into some technical/regulatory complexity   some line transformer manufacturers are scary - don't clearly state safety standards that their product meets -...

admittedly nit picking: no cartridge can track full scale 20 kHz - maybe 5 kHz for exotic cartridges, typically 2-3 kHz "power bandwidth" is the max at which ordinary records were cut   that cuts 12 dB or more off the...

if the TRS gnd connector gets too crowded then you can use another "clean star" "point" instead with heavy wire to the TRS gnd - a PCB gnd plane is one possibility   from a hum/safety gnd loop issue the better construction is...
