Sourcing Capacitor with color band question.

[ThePanda]

Does anyone know what these capacitors are called or where to source them?

I am making a bluesbreaker pcb and I am very curious about where Marshall even got these in 2022.

The value is 10pF and I believe it is film. Other boards use a poly film in place of it. The tolerance is 5% so maybe "Carbon Film Capacitor"?

They are axial (usually ceramic) capacitors designed to be installed by pick-and-place machines. Any capacitor type should sub fine there.

Holy crap Betty! That was quick! I had to google pick-and-place machines!
I do have a ceramic replacement ready, but do you know where to find these specific ones?
Now I am just curious.

I found some on Ebay using the search term "axial multilayer ceramic capacitor".

Oh my this is a wild rabbit hole.

Thanks again!

@Betty Wont I noticed this when I was trying to source a 22K pot that certain parts used in the OG Bluesbreaker pedal (and reissue) are European specific parts. This seems to be another one that disappeared from this side of the world because it is considered obsolete.

Seeing that c3 cap that looks like a resistor is new to me. That's pretty cool. I found some 0.1uf axial caps like c1 and c2 on Tayda. I've used them in big muffs I've built. It doesn't make any difference in the audio that I can tell as far as noise or anything, but they look cool.

Heck yeah it is all for the mojo.

Given that pots have loose tolerance, like ±20%, a 20K or 25K pot makes a suitable sub for a 22K pot.

I have a random handful of these 10nfs from electric goldmine. Not my photo tho. Loooove axial caps

How much mojo is in those?

I was also thinking of putting a resistor parallel with a 25K pot to make it around 22K.

180k == 21951.2195 Ohm
200k == 22222.2222 Ohm
(in a perfect world)

Or even a trim resistor to fine tune it.

I wonder if the new reissues have a run of the mill 25k linear tone pot or they went for a totally authentic reproduction with the 22k pot.

Authentic 22k. TheToneGeek did a teardown of one.
