    Class D driving horns, I'm ALL in.

    Same chip, different day...(TI TPA3255) It's like the TPA3255 is white cake. You can put whatever flavor frosting on the cake you want, chocolate, strawberry, maybe add nuts, but the cake is still white...

    Sick and tired of buying RCA cables for vintage gear

    I have some old Switchcraft interconnects that are over 60 years old. The center hot pin is a bit larger than more modern versions. So, if you try to use them with modern amps/receivers or whatever, you have to force them into the female jacks. They work fine with vintage gear from the era...

    Lance Cochrane tube amp - never got it working correctly

    For that kind of cash, you'd think he would at least spend the time to twist the heater wires.

    Snap, crackle, pop.

    When I was breadboarding single-ended tube amp circuits and had room to do it, I would swap in polypropylene capacitors for the filament/cathode bypass cap. I would have to parallel some of them to get the value I was shooting for. Large polyprop caps are expensive and large and I used what I...

    Why is the 10uF Audyn cap bridged across Muse cap and cathode resistor/resistors? Carbon Comp resistors in a modern tube amp?

    tube console vs "astro-sonic" solid state Magnavox

    Some friends' years ago had a Zenith beast of a console stereo that was hybrid. The receiver/preamplifier were tubes, and the power amp was SS. The thing was a garage blaster with good tone.
