Solderable Brenda^TM.

The bare wire Brenda^TM's are easily the best RCA's connectors in the world today.Their manufacturing costs make them considerably expensive but they represent the pinnacle of what can be achieved in an RCA connector.To augment this range of connectors another family of connectors has been designed.These are the Solderable Brenda^TM's.Brenda^TM connectors that use the same high quality materials and electroplate finish as their bare wire cousins. There is no point in making good designs from mediocre metals and finishes when everyone else is doing the same. In short, if there is to be anything dramatic in a new design in an existing domain then the result should be outstanding performance. This criteria is met in all the Brenda^TM Connectors available. The Solderable Brenda^TM is exceptional in its performance in comparison to other equivalent connectors. Exclusively because of both the materials used, engineering design, applied design theory  and in its quality of workmanship.

There are 2 Solderable Brenda^TM's:

The Brenda^TM B7.

"The Imperial"

The Brenda^TM B7 uses a signal pin similar to the bare wire Brenda^TM's that has been re-designed  to accept wire for soldering.
A long track of  nearly 9mm is located in the pin for securing the signal wire into place. There are 2 'bays' on the Brenda^TM B7.
The first bay is for the signal and the second bay is for the return.
The Return is soldered to the floor or the bridge or side of the second bay behind the signal bay.
The Brenda^TM B7 is 67mm long and 13mm in Diameter and uses Teflon as the main insulator.
After cable has been soldered into place,  heat shrink is applied to cover the exposed bays and the cable tail.
Optionally some urethane can be sprayed into the bays or the bays can be filled with neutral setting silicone
to fully seal the cable into the connector.
HeatShrink should always be applied after the assembly is completed.
The Brenda^TM B7 will accommodate cable diameters up to 11.0 mm in diameter ( 7/16" diameter ).

Utilising a 9mm long track in the signal pin for the signal wire and a double bridge at the rear for the return; the Brenda^TM B9  secures itself to the RCA chassis receptor with a Pure Copper locking barrell referred to as a: ClawLock. The ClawLock fully shields the contents of the B9 and is machined  from HCOFC:  ( high-conductivity oxygen free copper ), unlike any other equivalent locking device on any RCA connector on the market today or ever before. The Brenda^TM B9 is the only solderable RCA connector in the world that uses a Pure Copper ClawLock!  ( Many others are manufactured from aluminium or brass, steel and even plastic  Only the Brenda^TM  B2; B3 and B9 have Pure Copper ClawLocks. ). The firmness with which the ClawLock clamps the claws of the Brenda^TM B9 onto the appliance chassis receptor is identical to the Brenda^TM B3 and Brenda^TM B2. What this means is that the Brenda^TM B9 connector has a firm and secure anchoring for transmitting its signal from interconnect cable to the appliance with no effects from vibrations or micro-arcing or ringing due to a loose fit or other unnecessary rotating locking mechanisms. The Brenda^TM B9 will accommodate interconnect cables up to 13.0mm ( 1/2ins ) in diameter and secures the cable into place with 3 set screws.

Soldering.

When soldering wires to the B9 RCA ensure you are using a very hot iron! As the B9 is made from Pure Copper it conducts heat rapidly! Hence you need to ensure that your iron is at least >60 watts; has a fine tip and you have a heat proof   method of handling the connectors while securing your signal wires into the connector. Be Careful! If you are uncertain then get a professional electrician with cable assembly experience to do the assembly for you.

COMMON CHARACTERISTICS FOR THE SOLDERABLE BRENDA'S^TM.

*    All solderable Brenda^TM's are fabricated from  Solid billet High Conductivity Oxygen Free Copper ( HCOFC); Pure Copper > 99.94%Cu!
*    All Solderable Brenda^TM's use Teflon as the  insulator between the polarities.
*    All Solderable Brenda^TM's are electroplated with 15.0+ microns of pure Silver and then
     1.0+ micron of Hard Gold Plate ( 23.5 Karat ).
*    All Solderable Brenda^TM's' signal pins' are electroplated with a total of 3.0+ microns of Hard Gold Plate ( 23.5 Karat ).

FULL ENVELOPE EARTHING GEOMETRY

The Brenda^TM B7, on contact with the appliance chassis socket, delivers a full envelope earthing geometry around the chassis socket and so results in an exceptionally quiet background.
The Brenda^TM B9 delivers the same full envelope earthing geometry, but for the full length of the ClawLock shield. This results in an even quieter background.
All Brenda^TM connectors offer a similar full envelope earthing geometry. This design property results from the Claw Tongs of the Brenda^TM's fully enveloping the chassis socket with Pure Copper. Being made fully from Pure Copper enables the entire   outer Copper Body of both the Brenda^TM B7 and Brenda^TM B9 to act as an optimum earthing shield for both the return wire and against radio frequency and electromagnetic radiation frequencies that impinge on the ability of a connector to keep background noise quieter than the signal it carries.
The result for the listener is a greater dynamic range for the music being listened to.

Performance.

It's the combination of superb materials, excellent engineering and attention to design detail that give these RCA connectors the edge over their rivals. Their performance is surprisingly close to the Bare-Wire Brenda^TM's; notwithstanding the obvious advantage that high-pressure bare wire securement can do for audio performance. Whatever cable used the performance is superior, in every instance, to any brass connector.

Sam N Review with Furutech  OCC cable

"The Brendas raised the quality of the cable to a new height. I had used the top-tier solderless WBT, the top solderless Furutech, and the top Vampire (pure cooper) connectors with the same cable.

The Brendas provided a greater soundstage, significantly improved transparency, clearer and more distinct bass, a solid and palpable midrange, and extremely refined highs. "

Note1

    If you are intending to use Hot Glue to fill the void in the Brenda^TM connector do not allow contact with  your bare skin while the Brenda^TMconnectors are hot.  Copper is not only an excellent electrical conductor ( second only to Silver )  it is the second best thermal conductor ( Silver being the best ).
This applies equally to the  B7; B9.
