If anyone knows where I can find (or can source for me and trans-ship) an Alps RK097, audio taper, 50K, with and/or without the SPST switch, please let me know. This is the same Pot that Tangent sells, but the 50K flavor. I would want about a dozen or so, which would make global mailing feasible.

I RMAA tested my Pint today. My results were interesting enough that I thought I would post them. It may help those trying to tame the 8397 beast and it illustrates the value of this cranky chip. I think any future efforts will be well rewarded... My Pint configuration is as follows: 2x...

I am looking for the thin gold grounding lug that comes with the Cardas CTFA RCA jacks. Dayton audio sells essentially the same jack with the same grounding lug. If anyone has a spare or can tell me where they can be purchased, please PM me. I have one that magically disappeared while...

I want to make a tread brick in a box approximately 2.5"W x 2"H x 5"L. I found this box. It is the right size, but it has card slots cut into the ends. I want a box without the card slots because I want to install a Qualtek IEC inlet and a rocker switch in the side panel. I'm concerned that the...

A couple issues with my PPA part selection; maybe someone(s) has some insight or ideas. My PPA will include a battery board in the Hammond 1455N1601BK case (4x6.3x2), pretty much as Tangent suggests, with the battery board in the 3rd slot from the bottom and the amp board hopefully fitting in...

After burning out a few too many DMM fuses, I got to thinking about a simple current limiter that I could plug in line into the probe, or to my power source, or maybe build a tread that was current limited. My thinking was to limit the PSU current to the DMM max current, which is 100ma or 200ma...

I am setting up a PPA with battery board. I'm looking at www.thomasdistributing.com offersings and I see the more or less old standard Sanyo 900mAH batteries and also Accupower 1000mAH. Anyone have any experience with the Accupower batteries???

A couple quick questions on the battery board and PPA.... I am looking at configuring it for about a 3 hour charge- I don't want to deal with heavy supply current issues. Using AAA's. I will use a Steps for power. 1) The docs allude to issues with filling the board with 18 batteries. Can I...

I managed to corrupt a fairly complex ExpressPCB schematic file. Somehow I ended up with an errant pin from a component that could not be deleted. This resulted in an error that prevented the file from saving, but the previously saved file had the same error. Very strange. Anyway... I sent...

I have built a Millet and M3 for desktop use, both Steps powered. I also built a Portable Pimeta but that is not part of the equation. I've been reading the Dynalo threads and I am wondering what this might add to my "collection". Not sure if I am trying to talk myself into it or out of it...

I am using a 5G iPod with iTunes on a current version of Windows XP. After plugging in the iPod to USB and updating, the iPod will rarely go back to play mode. It gets "stuck" with the updating screen displayed. If I try to eject it from iTunes it will not let me, telling me that another app is...

When pots are used for circuits such as bass boost, where it is acting as a variable resistor and not a voltage divider, only one side of the pot, plus the wiper is needed. I have noticed that circuits such as the PPA and M3 tie the unused side of the pot to the wiper. What is the purpose of...

Hi All, I sat down the other night to learn how to use ExpressSCH and ExpressPCB. I copied Tangent's CMoy schematic and laid out a PCB just for practice. After all that work I might even order some boards Here it is.... Or view a high res image here...

I am just about to start building a Pimeta in a Serpac H67 case and I want to add bass boost. I saw your solution here: http://www6.head-fi.org/forums/showp...0&postcount=12 I think that is a very slick "breadboard" solution and it fits with my overall plans to breadboard the Pimeta board...

I want to add an outboard soundcard to my laptop. Mainly I want to be able to do accurate RMAA tests on the amps I build. I would also use it to rip some old LPs to digital (some day). I checked M-Audios web site and they list it for $349, which is a bit pricey for my purposes. I investigated...

After building a cmoy, I found it might be impossible to fit two batteries in a mint tin using the RS 276-150 protoboard with an ALPS97 pot because this pot is very long... I was inspired by an image posted here (I think) by tyre and built his version, tweaked to do what I wanted with the...

I would like to, for example, socket R3 to tinker with the gain. I will be using the RS 276-0150 protoboard recommended by Tangent. Could someone point me to a part, preferably Mouser or Digikey, or Rat Shack. Also curious what people are doing to Buffer CMOY type circuits with the 634...
