Amp Internal Wire


Hi Gents, has anyone have any experience with upgrading amp or preamp internal signal wire? Most older equipment seems to have thin maybe sometimes poor internal wiring. In the world of OFC/OCC/Sterling and even more exotic wire available these days, any experiments done using this internally on components swapping out the cheap?

Lots of discussion about doing this with speakers, but never with components I've seen. For instance, I am thinking about replacing copper 'appliance' wire in an old Bryston with 14awg sterling from the board to the speaker binding post board.

 

Any thoughts?

The first time you take a vintage piece apart, you may be shocked at the simple quality and small diameter wires you find.

Keep in mind, this is within the pieces that produced results that made the reputations of these great companies.

You mentioned amps, but I will never forget what I found inside the Fisher/Electro-Voice speakers I inherited, (made in 1958)

The wires looked just like these:

just came across this tidbit

"They decided to focus their business on audio products. The company designed a PA system for Notre Dame football coach Knute Rockne. Rockne, who had difficulty being heard at football practices due to health problems that affected his voice, called the new PA system his "electric voice". Rockne’s remark inspired the company’s name. On June 1, 1930, Burroughs and Kahn incorporated under the name "Electro-Voice".[2][3]"

 

Amp Internal Wire Any thoughts?

I like the internal wire this company uses in their amps. See below:

amplifiers in the world.

Manufacturing Process 

Our amplifiers are assembled and wired by hand at our factory in Massachusetts. Analog sections of our products utilize individual, discrete components—no chips!—and all wiring is point-to-point. These techniques are labor-intensive and far more costly than what you’ll find in throw-away electronics, but ensure a lifetime of reliable performance and serviceability.

 

Completely Hand Wired 

Wiring and soldering of all Rogers products meet Military Standard 2000 requirements—sometimes called “Mil-Spec”. All our assembly technicians are trained and tested on these high standards.
 

 

Dual Power Supply Circuits 

Dual linear power supplies can easily handle large dynamic transitions in the audio signal, while maintaining a smooth and clear midrange. Vocals are presented with a truly rich and warm feel.
 

 

Internal Wiring 

Wiring is the signal path of any amplifier, and it does make a difference in both durability and performance. We use 18 gauge Military Standard 16878 teflon coated, silver plated copper wire. This is expensive (besides being a mouthful!), but is used in mission-critical applications like the Navy’s AEGIS cruisers. Teflon coating provides heat-protection for decades, where common PVC-coated wire will crack and degrade over time. The 18 gauge wire provides greater signal capability than a trace on a printed circuit board, and ensures that the amplifier will be stable under any condition, and will never limit the dynamic range or transient abilities of your amp.

 

MIL16878 is PTFE coated. You can buy 16878 inexpensively. I have used it before because I needed the voltage rating for a given total diameter. It was not very expensive. Silver plating would add cost, but is overkill compared to tinned.


Standard irradiated PVC wire that is not exposed to the sun or very high temperature is going to last 50+ years. Using a heat gun that goes up to 300+ Celsius is not very representative of normal operation. For tube amps, sure, why not, if you are worried about wire routing and heat. It is < $1.00/foot even in a 100 foot spool/18 awg. Not going to break the bank on a DIY.

@theaudiomaniac

Like I said, @holmz , all yours. Crazy posts draw out crazy people.

How would we know it is crazy?
There are no measurements or rational indicators to go by.

I can see inductors and transformers making a difference.
And the even capacitors and wire dielectrics.
It would be nice if someone could quantify some aspect of it.

 

All that needs to be done is some before and after of the DC power supply rail voltage. Without that, it seems like a story or myth.
But if it has some damage or needs rewiring, then changing it probably makes some sense.

They use that Tefzel stuff in plane and race cars, and it is also great at not chaffing through the insulation. But an amplifier is not usually vibrating like a race car or fighter jet, or rocket launch.

I use it myself, but it will not make an amplifier magic without the circuit design providing some of the magic.

It is much the same way that the most expensive saffron in the world, will not make a pork roast taste any better. But it might help an Indian curry .
