Power tubes like 6 Volts.

Well it doesn't matter a great deal on low gain builds. As more stages are used, the hum/noise floor increases, requiring adoption of these strategies up to a full D.C. heater supply for preamp tubes.

Elevating fights hum by eliminating hum induced in the cathode by the heater.
Twisting reduces hum by reducing radiated hum, by
, as RJ said, antiphase nulling, capacitance to ground, etc.
So both strategies combined will give less hum.

A choke input filter should have a very small cap at the input to keep a small voltage on the inductor between cycles to avoid a complete collapse of the magnetic field, and the attendant noise from the current dump.

I wonder what freight would cost?

Really, the tone relies on 2 picoFarads? Your ears are better than mine Miles.

Oh the humanity!

Still, not great engineering.

Seems like mathematicians abandoning exponents. At least there not using Ångstroms.

Oh, I agree with ya there. Measuring larger distances, especially without my bench glasses, would be headache inducing.

I'm still not buying any overpriced red transformers. If they're the only xfmr company left I'll eat crow and go sandy state.

More popcorn! Eleven pages and not slowing down. As divisive as the other internet puzzle, is this dress blue or gold.

I like working in Metric. Precision in sub- meter lengths is better/faster. We should have gone metric in '72, when Nixon said we were converting. Of course industry wasn't interested in the changes expense. Hence the 355 mL beverage cans. Still 12 ounces but now we're metric!

Odd they used brown, blue.and green for.a.secondary winding. Being generally used for primary wiring. Is the xfmr damaged? Wires less than an Ohm sound shorted, no?

And lately reality needs dithering, or more bias to calm it down a skosh.* I think more negative feedback. *from Japanese sukoshi [skoh shee] meaning "a tiny bit" Kore wa nihonese des ka? I remember little of the Japanese I learned as a youth in Hawaii. High bias voltage, Negative Feedback, and a r...
