Silver Rock TVC
The Silver Rock Transformer Volume Control (TVC)
using Silver Rock magnetics and copper wire
Silver Rock level magnetics / copper wire TVC in wooden cabinet
Many of our customers have made inquiries for a copper wire Transformer Volume Control (TVC) with the same exceptional magnetic circuit as the Silver Rock with silver wires.
Here it is!
Even if the silver wire further improves the sound, you get a substantial part of the magic even with the copper wire, which makes it more affordable.
Passive Transformer Volume Control
First we would like to explain our general philosophy :
There always is one optimum for a given problem. It costs tremendous amounts of time to find it, but this is the only way to make real progress. If you want a cheap solution for your potentiometer in your sound system, then use carbon pots.
They are more neutral than the expensive plastic ones and of course much cheaper.
If however you want the best possible solution to your potentiometer problem, then you should try our silver wired transformer - potentiometer that really is a world apart from other volume setting devices.
Some years ago, when we still were believing that we can achieve good sound with conventional potentiometers, we made a 100 Kohms 24 position stepped potentiometer using Tantalum resistors. This was a lot of work and we were proud of it.
We wanted to see how much better it was comparing it to a surplus graphite type pot.
Even if it was very difficult to admit, the graphite type was better sounding and we decided that we need some fundamental research to be performed.
The first trials with transformer-based systems were rather successful and we went on into that direction ending up with custom made iron as well as custom made silver wire.
This potentiometer clearly shows that it is useless to expect resistive systems to perform without major sound deterioration.
We have noticed that putting resistors in series with the sound signal always results in dynamic constriction and loss of details.
On top of that, a transformer enables the discontinuity of grounds, which helps to keep RF and LF noise as low as possible.
