Two clarifications ...

Two caps in series are only 1/4 the sum of the values if the values of both caps are the same.
Two resistors in parallel are only 1/4 the sum of the values if the values of both resistors are the same.

1/4???

Wasn't it 1/2?

Pretty sure speakers simply act like resistors for the purpose of calculating cab ohms

Which is why with 16 ohm speakers in a quad, you can wire them:
Stereo parallel @ 8ohm 8 ohm
Parallel x parallel = 8 parallel w/ 8 = 4ohm
Series parallel / parallel series = 8 series with 8 = 16 ohm


Oh wait you said 1/4 the sum lol. True. Same as 1/2 the value of one of the matched pair.

No, the OP said 1/4 the SUM. I just replied to it. Yes, same as 1/2 ...

Not going to mention whole fractions vs. floating point numbers issue...

But how do you visualize farads?

I don’t. I visualize .05 as being half of .1

Half of .05 (.047) is .025 (.022), and so on. Nanofarads doesn’t add anything to the mix.

I’m fine with decimals.

Except integers being easier to remember, discuss and write down. That's why units are scaled.

I think you're just trying to make an argument for the sake of argument...

That's a great article. Good read for all the cork sniffers that are die-hard vintage cap promoters (yes, like Guitaryellow).

Yeah, it nails all the hype-
I had planned to do a blind study like this until I found this page-

But you wouldn't believe the number of mods we are forced to do with expensive, old junk because the customer is convinced they will sound better- And they ALWAYS say it ultimately sounds better because of placebo- so we can't say much without losing our 'cred'.

And it's not just us poor little guitarists that get duped- check out this blind study for Stradivarius violins-

Re: Capacitors

I think they have $1200 speaker cables too if you are interested.

Back to caps, cheapo ceramic disc caps will work fine for tone controls (says the blasphemer) but don't forget the 0 (.047, not .47) it's an important place holder.

They have a series that STARTS at $5000. And they aint near the most expensive snake-oil dealer around. Not by a long shot.

Yeah back to reality, the ceramics are perfectly good from an electrical POV, but they are more fragile and can dry out and crack relatively easily- So if you are new to caps, it does make sense to spend a little more to get Polyester/polypropylene film - generally called orange drops- you will spend a couple of dollars if you aren't buying in bulk, but they are considerable tougher and there have been times, working in small cavities, where I would have crushed a ceramic disk, but I've never broken an orange drop.

Re: Capacitors

I'll agree with reliability being a reason to go with something else, although I don't think I've ever destroyed a disc using it as a tone control. Don't remember what I used last time, whatever was laying around, probably polyester.

$45,000.00 for a 2 meter pair ...

I'm pretty sure that pair of speaker cables is worth more than all my worldly possessions, I'm not sure what part of that statement is more sad, but I'm pretty sure it is true and not by a small margin.

And that's just for 2 meters. Check out the prices as the lengths increase. There's a drop down menu on that page I linked.

Some people have more money than sense, me thinks. But I'm sure the people who actually spend that type of money on cables would just say that I envy them.
 
Re: Capacitors

I put a paper in oil cap in my RG2

It sounds great

But it could be the Duncans
Or the treble bleed
Or the super switch
Or the Triple shot rings
Or the Carvin Tuners
Etc....etc

No, I’m telling you what I find easier to use.

And you can’t “discuss and write down” fractions or decimals? Lol. That didn’t even make sense.

Fractional inches are particularly easy... half of 3/4 is 3/8... etc.

I wonder what response I'd got if I send a crosscut drawing of road plans with all the measures in kilometres.

Width: 0.0042 km
Slopes: 0.0005 km per side
Outer slope 0.001 km
Ditch depht 0.0015 km
Gravel depht 0.00002 km

:lmao:
