24 Steps Volume Attenuator (Dale Resistors-Full Balanced)

[YFW]

24 Steps Volume Attenuator 10K/100K/250K (Dale Resistors),
Full Balanced Design/Assembled
High Quality/Ulra Low Noise/Clear Sound
Ladder Type/Stereo
69.99 USD Free Shipping.
Please contact next.ps@gmail.com or visit my ebay store.

Advantage of Ladder Type Volume:
In Ladder Type Volume control, input signal only pass through two fixed resister at a time. Hence noise introduced is much reduced compared with other type of configuration such as serial type. Although serial type stepper volume is simpler to construct, input signal has to pass through many resistors, noise is thus accumulated.
¡@
Ladder Type volume control eliminate the problem of low accuracy, low stability, poor channel matching, high noise .... in traditional potentialmeter (variable resistor -VR) used in general audio equipment.

Made from :
1% High accuracy & low noise Vishay Dale RN60D metal film resistor
Perfect workmanship
7N high purity OCC copper wire
WBT audio grade high silver content solder
Other Value Available (100K, 250K or Full Balanced Type)

Hi, I remember seeing these in Asia a while back that come in an 8 deck version for a balance ladder attuenator. Is there a fully balanced stereo version available in 10K?

Thank you,

-David

 

[YFW]

Yes,it's fully balanced stereo.
We have 10K/100K/250K in stock.

 

[hifimaker]

This version looks like it's for balanced single ended stereo. I'm looking for a fully balanced version.

Right channel + and -
Left Channel + and -

If this version is fully balanced stereo than it's a shunt or series attuenator rather than a ladder type. A true ladder would take 8 decks, 2 per + - signal for each channel.

I know what you mean.It's truely fully balanced stereo.

You could check the photo and will found the resistors stacked by layers and the switch is also customized(re-arrangement) for this purpose.

 

[YFW]

It's ladder Type.

 

[hifimaker]

Yes, I see! I did not see the resistors cleverly stacked on top of each other. They are all there.

I'd like to buy one in 10K. I'll go to your ebay store.

Thank you,

-David

 

[YFW]

Thanks.
It's not easy to manufacture this products and we only have limited quantiy to sell.
(And we won't manufacture this in the futur.....it's really a HARD WORK!)

hi

do you have a datasheet or list of output resistances at each step.

thanks

 

[elviukai]

hi there I would take balanced version 20-100kohm 2-3pieces. how can I find yours ebay store?

 

[YFW]

We have 10K,100K and 250K in stock and ebay store.

Hi David,

I think this picture makes it clear.

Hi David,

I think this picture makes it clear.

i see the price increased, and I got the last 10k one maybe I can get some bonus Rifa caps since the price went up?!

 

[YFW]

Yes,it's the last one for 10K.
Now we only have 100K and 250K in stock.
And still have some 10K/UN-balanced type.

hi, I bought a 10k balanced for 70 usd on ebay, but will let it go if someone else wants it , or relisting (username : 2rnagic , we skipped ebay procedure at the end)

 

[flshzug]

forget to say that this 10k balanced is located in Taiwan yet, cuz i dont really want it so probably wont pay for it at all .

(very nice thing that some dear moderator put my account into infantile state becaus some comment in digital topic , revising my comments one by one so I cannot use EDIT button uh-oh )

 

[YFW]

OK,Thanks.

 

[Ted205]

hi

do you have a datasheet or list of output resistances at each step.

thanks

So no specs available?

I'm not really prepared to purchase without knowing what i'm buying

 

[YFW]

It's ladder Type which means it will maintain the constant resistance at each step.

 

[AndrewT]

and what are the steps and the resistor/channel balance accuracy?
