Let's talk about capacitors

[yngzaklynch]

I'm very probably gonna do this. The mods described here http://marshallvintagemodern.com/viewto ... f=1&t=7819 only involves switching out 2 caps. So with this in mind can anyone recommend really good caps?

Sozos, Mallory 150s... sound good in a Marshall...

Thanks bud. How about Orange Drops?

No problem...
Orange drops confuse the shit out of me. There are like 1000 different OD caps. They're made by different companies.
The ones I got are made by SBE 715P/716P and the PS series sound good , but they' have a spikey high-end. It's hard to tell sometimes how they're going to sound until you try them. I've tried a bunch of them at this point. All I can say is the DO sound different and it's noticeable. Particularly early on in the circuit.

try solen fast. but unless youve done htis a lot you prob wont hear a diff.

Yeah Jim,
I heard those are great too. I don't have any experience with them so i can't comment.

My amp has a combination of solen fast caps, sozo vintage, ceramic disk and silver mica caps...

where are you using the Solen's Steve?

where are you using the Solen's Steve?

Basically, anywhere I needed 630V or couldn't find the value I needed in Sozo Vintage...

Interesting. I need to give these a shot at some point.

Wonder how much of a difference this mod will make???

Well for one thing, the frequencies that get boosted are going to be different. Also, the quality and materials of the capacitors will make a difference as well. Going from .0022 to .022 (or vice-versa) coupling will make a noticeable difference. .0022 will be brighter than .022 cap.

Hmmmmm thanks.

 

[joepete77]

I liked the orange drops the least , sozo sounded best with marshalls

 

[yngzaklynch]

Well it looks like I can order the .0022 400v mustard from Sozo but still need to find the 1uF/25V radial electrolytic cap

nobody is going to like this, but sometimes you have to point out that the emperor actually has no clothes. That being said, you must remember this: (and I'm really simplifying things here) tone does not pass through the capacitors. The capacitor, by it's very nature does one thing: it shunts/diverts some signal to the ground. The plus/input side of the cap connects to the input signal. The negative/output side of the cap connects to the ground. If tone were to pass through the cap, it would not have one leg that connects to the ground. Think about it. The hot/plus side of the circuit carries the signal. If we use a capacitor to direct some signal out of the path to the ground side, none of the signal passing through the cap ever reaches the input side of the amp. The capacitor VALUE, not composition (material it is made of) determines what frequencies are diverted to ground (and thus do not pass through the amp).

I don't think you know what you are talking about honestly. I believe this holds true for all components of any type in parallel configuration, meaning one terminal is connected to the signal path and the other terminal is connected to circuit ground or return path and would not be a unique property of capacitors. How about coupling capacitors with the cathode soldered to the forward signal path? The capacitor is then in series. Plus, not all capacitors have a negative and positive side. Those are polarized capacitors, and make up about one tenth of the entire capacitor catalogue.

I would need a schematic to know exactly what component the mod is referring to, but from the things mentioned in this thread, I can only imagine that it is either a grid coupling cap, or a cathode bypass cap. Both of which readily pass AC signal.
