I'm not sure if these are real. Take a look at this:

http://www5.head-fi.org/forums/showt...threadid=11704

I bought one (before I'd seen that thread), and it seems to work okay. It's got some odd quirks, though. For instance, I'm using it as a volume control, and I get maximum volume at about 70% rotation -- beyond that the volume goes down a little. Could just be I wired it up wrong, though.

In the end, it sounds fine, and it's relatively cheap, so even if it's not really Alps it might still be a good deal.

Even if they are fake.

An attenuator for this price is great.



Also seems like you can order them direct for a bit of savings.

Wai Kei Leung says that the following stepped attenuator values are available: 10k 20k 50k 100k 250k 500k. They are $6 each with a minimum order of 4.

What a long thread over at head-fi. They are clearly not Alps pots, and are made by this company:
http://www.cxzhenwei.com/english/cpzs-pro01.htm

The action is said to not be very good and half the people claimed that they clicked between positions.

Nevertheless, $6 seems to be a decent deal for a stepped attenuator.

The knob is also difficult to deal with. It is too long for most knobs, and when you crop it shorter, it is difficult to get a knob that fits it properly.

I have a black beauty detented stereo attenuator in my amplifier now, which I wish I could find more of for a good deal. I paid $35 for it from Percyaudio.

Hi,

I have one of these e-bay volume controls in service and I found that there is a little bit of contact bounce between detented positions.

I replaced my 100K carbon pot with a 100K alps? and I do not have to turn the new control up as much to get volume. Maybe the 100K rating is not that accurate.

When the volume control is set it works very well. I would buy another.

Yea.. I have a pair of these from eBay.. Starts popping at about 9:00 position through about 11:00. I have noticed that the more I use them, the more they pop... Will replace with higher quality when time permits..

btw, this is my second set

Spray them with contact cleaner inside, it may help.

[Ciscokid]

Yes, I tried that and it did help just a little. However, didn't take long to get back to fairly loud popping..

Anyhow, I don't change the volume that often..

I bought an ALPS 50K on Ebay from MYADAPTER.

It showed up (from Hong Kong) in good time and I though I had a bargain.

The ALPS snapped crackeled and poped. It was breaking the contacks. I had the ALPs in the feedback loop of an 825 OP amp circuit and promply blew a test speaker. The ALPS was $12.00

I then wen to a Noble (for 19.95) and it works great.

I took the ALPS apart and cleaned it with a pencil eracer. Still broke contact.

I had $12.00 worth of fun and get to complain.

Almost as good as if it worked.
