These are the same resistors that I use to correct AC filament voltages. I now attribute the fine sound of my amps to these resistors. At first I thought it was just dumb luck.

The Pacific wirewounds are specified at two different temperature levels.
The 7-eleven ones of the Big Bybees are not standard production items, endcaps are different for one.

"AGAIN, let me remind you that until Ottala showed the way with TIM, people swore by their low THD... and a LOT of gear with really good THD specs sounded like ****! "
The fact is the audio engineering community was years behind in understanding the concepts of slew rate and full power bandwidth. They also tended to ignore the rest of us.

It's been fun reading this contentious thread, and although I've avoided jumping in - here goes...
Disclaimer: I'm a EE and pretty skeptical of the Bybee since I don't understand the science behind it.
That said, I'm just as skeptical that double blind listening is useful. There are a lot of psychoacoustics involved in listening. Speech, music, noise, whatever - your brain does a lot of interpolation and reconstruction. That's why several different people can get several different sets of lyrics from the same song. IM(notso)HO, serious extended listening is a must to determine sound quality. I've personally been involved in AB setups between <crap> and <really good stuff> that could not produce a consensus on which was better when using fairly short listening intervals. With extended listening, there was no doubt as to which you'd want to listen to, in fact you wouldn't believe that there was any question as to which was better.
Sorry if this has been covered earlier in the thread, I think I've only read about a thousand posts between this and the previous Bybee thread.
Regards,
Jim

Which would all be relevant if the testing were to be for the purpose of assessing which sounds best. However, there is still no emperical evidence (as against anecdotal) that a difference (good or bad) can be heard reliably and repeatably, and therefore no evidence that a real difference exists.
First things first in other words.
Quality after that (as in subjective quality) is a red herring since no two people have the same hearing or perception of the sound image thet is heard. Therefore, once you get past gross errors in sound the matter is entirely one of taste. IMHO.
I'll ignore that comment 🙂
Scott,
Some do, some actually don't. I used to have a nice bookshelf, but there are far fewer books coming out these days. If you want to mention articles, the magazines are just about gone.
So the new source is the web. The problem is that any idiot can show up. I know that very very well!
However as far as books go I nominate for a good bookshelf at least:
The Radiotron Designers Handbook
Acoustical Engineering
Digital Signal Processing
Architectural Acoustics
Handbook of Noise Control
Acoustics
Op Amp Applications Handbook
The Art of Electronics
Machinery's Handbook
CRC Tables
The Theory Of Sound
On the Sensations of Tone
Just looking at this list, it should take several years to really understand them!

For more amusement, there is more at AA:

From the AC thread and photos, it would be nice to know what the stuff around the resistor really is. That seems to be the secret ingredient.

Yes, but how good could it be since I also have an article in it🙂!
Worse yet, if you google my topic in it today you will get no hits. Wait a year and there will be lots of people who invented it!
Jan is producing a useful publication, many start out by casual hobby interest and that can lead to real studies.
I can't be sure Cal, but there is a sticky blue covering that I have never been able to trace. Anyone seriously TRY to source the EXACT resistor that Jack Bybee is using? I can't find it.
