    Hi,
    I can't find in Italy this potentiometer.
    Can you send me an electric drawing of the pin to replace it with a similar ? Is it a single potentiometer or double? Why it has seven pins ? Simple potentiometer, normally, has 3 pins.
    Listening a FM station, I heard a 1000 Hz noise, it depends by the potentiometer, too?

    on line, too. In italy I can't find it.
    May I replace with a normal potentiometer?

    Hey, check the link I gave you, it might not be useless after all.



    Look if you can find a similiar one there. Or then a local electronics store.

This can be replaced by a generic control and should be available from any electronics parts supplier. There are two main types of these that differ only in the way they are mounted. When you look for the replacement, you will need to specify the direction of the pins. In other words, are the pins inline with the main shaft or are they at a right angle. Since you are in Italy, I don't know any distributors there, but this should be a common enough part to be found just about anywhere. The indication A20K indicates that this is an Audio Taper valued at 20K which is 20,000 ohms.

Good luck.

    The pot that you have is a double or stereo pot. There is an extra ground pin. Try searching for Alpha as that is a large manufacturer of these components. These should be readily available from any mail-order electronics house.

Replacement part or schematic for Cambridge Soundworks computer speakers


I'm in the same predicament! I found this - it seems close, though the pins seem to be spaced closer together, but it looks like they might be bent to fit the wider PC board spacing. The rotating shaft also seems smaller - the original is larger than 1/4".
What do you think?

Is there a way to use the Altec Lansing VS4121 Subwoofer as a stand alone?


Normally these low end systems components that depend on each other and cannot be interchangeable from other system. So if one of the components (sub woofer or right control satellite speaker) breaks or gets lost the whole system is unusable...
I was in the same situation. Got a sub woofer from VS4121 without original satellite speakers. I acquired satellite speakers from Altec Lansing 251 which used same connectors but the internal wiring was different and incompatible out of the box. Speakers are also glued together so it is impossible to open without damaging it. Not to mention there is no service documentation anywhere..
But if you like electronics you can try to make something based on the information bellow:
Altec Lansing VS4121 connector pinout
If you take the male connector (from right satellite speaker) and look at the pins and number them first row from left to right pins 1-3, second row pins 4-7, the bottom row pins 8-9 and the circle enclosure as 0
0 - Ground
1 - Speaker Right
2 - Treble (seems just like voltage control but may need to be confirmed: Min=0V; Max=voltage from Volume control Pin 9)
3 - Head Set Right
4 - Bass signal (not sure what the exact original design is as I have not opened the speaker) But seems like they use 50K potentiometer and some sort of RC low pass filter configuration. When potentiometer is set to Min it is shorted with ground. When set to Max it is taking signal from Right and Left Head Set (pins 3 and 5) combined through some larger resistors and low pass filter.
5 - Head Set Left
6 - Ground for Head set (grounds 0 and 6 seems to be connected in the subwofer but within the right satelite speaker they seem to be isolated with separate leads to sub)
7 - Power ON/OFF. When OFF or head set jack plugged = 0V; When ON and head set jack unplugged = 5V
8 - 5V Power in
9 - Volume (min=0V; max=5V). It seems they use 50K potentiometer but probably anything >10k should work.
At minimum for standalone sub woofer you will need to implement:
- Power On.Off (switch between pins 8,7)
- Volume control (50k potentiometer (probably anything beteen 10k and 50k will do)between pin 7 and 0 with variable output to pin 9
- Bass control - join two resistors R (I used 7k) and lets call this join point A. Attach other ends of the resistors to pins 3 and 5 respectively. Attach 50k potentiometer (I used 10k) between point A and ground 0. Attach Variable pin of the potentiometer to pin 4 (Bass input signal). Attach capacitor C between Pin 4 and Ground pin 0 (I used Electrolytic 1uF with negative end to ground) . Resistor R and capacitor C should make simple passive low pass filter (Google for formula) that should bypass anf frequency higher than 80-120Hz to ground and feed frequencies lower than 80-120Hz to pin 4.
PS: I managed to hack 251 control satellite speaker to somewhat work with VS 4121 Subwoofer but that is another subject. All electronic parts were salvaged from old broken TV so total cost was $0 but took several days of tinkering for speakers that I could buy used for $10-20 :)

I have a scratchy pot on my volume on my 003 factory...Can i clean it?? Or replace it myself with out the high cost shipping??


For those who still suffer from crackling potmeter in DigiDesign 003: Well, this potmeter is not the top of the line.
I made weeks of researches to repair my friend's DigiDesign003 crackling headphone+mainvolume potentiometers. We decided to find replacement-parts which is much cheaper than the $10 assumed here above. Here's the significant part of what I found (posted at avid forum as well):

I attached an Excel-datasheet-screenhot which contains all the possible candidates, however I couldn't find some of the potentiometers at distributors, USA people may have better luck to find the most fitting one. Fortunately BI Technologies in UK produces a rotary audio-potmeter line which fits the 14mm dimensions of the Digi003 built-in potentiometers. (Our local distributors could only acquire a similar to similar P140KH1-20AR20K from BI Technologies, it needed a little bit of tweaking, rasping, but it now operates fine and is durable - 30000 turns - on paper .)

The extracted info of the Excel, the most fitting models (datasheets help to find correct/closest part-number):
-BI Technologies(UK) P140KH-F25AR20K (confirmed to exist by BI contact but distributors haven't ordered this yet, needs 9 weeks of shipping if you manage to order it. Above I mention, BI P140KH1-20AR20K is proven to work and BI potmeters bear 30000 turns, 2 times more than other brands.)
-Bourns(USA) PTV142B40Y025AA203 (unfortunately DigiKey and Bourns told it's obsolete)
-Noble(USA) XV014112GPV-25F-15A20K (seems very similar to the original DigiDesign003 potmeter. I have no info, how to order. Maybe directly from manufacturer.)
-Alpha(USA) 3RP/1416G-CD1-D20K (probably orderable from Alpha directly by using their web-interface to assemble part-number.)
-Alpha(Taiwan) RV142F-40-25A-A20K ? (datasheet/xls may help with correct partnumber)
-Alps(Japan) RK14K12C0A0T (its value is 50kOhm, not the best replacement-candidate)

Distributors I found (in approximate order from biggest to smallest):
USA: Arrow, DigiKey, Mouser (shipping outside USA costs around $60)
Europe: Farnell/Newark, RS-online, Distrelec, Conrad, Allied, TME

Some last observations, advices to select correct part:
-must be 2 * 20kOhm, logarithmic scale for audio application (A taper)
-these 14mm dual 'audio' potmeters seem to have the same 'standard' pinout, but 'tone' (bass/treble) potmeters has a bit difference: common point is separated to 1st and 2nd leg. We simply cut the end of 1st leg to be short (not to reach PCB) and solder it to 2nd leg (see 1st photo), and it seemed to be perfect 'audio' potmeter substitute in our case. Check out datasheets or my excel for pinout-details.
-the shaft/rod of the potmeter should be 'flat' type with cca. 6mm diameter, 4.5mm flatted-part thickness and 12mm flatted-part length.
-the complete potentiometer should be around 25mm tall. datasheets state it as 'L' parameter, but be careful, it differs for potmeters with bearings, where it refers to the shaft-length. Drawings in atasheets make it clear hopefully. It seems that our potentiometer which unfortunately had bearing, still fits into the DigiDesign003 fine...
-most of the times the orientation of these panel-potmeters are referred to as 'vertical' which means they stand vertically and their legs are bent to fall into the PCB, as well as their securing point is at the bottom. The drawings in datasheets help to identify if its that way.

I hope this ordering & technical info was a little bit of help for some people. Sorry in advance if any of the presented info here were incorrect/misleading, I tried my best, and don't take any responsibility for the correctness, so use the info at your own risk...

Good luck, if you decide to acquire and replace the potmeter for yourself... For non-technical people I advise to ask someone skilled in soldering because it's hard to desolder the original potentiometers from the Digi003's 2-sided panel... Soldering flux comes handy to lower the melting temperature of tin. Flux can be cleaned with acetone after soldering the new pots in.

It would be useful if you might post any results here if you used any of the pots above... b5f78999-5206-4219-9814-477b70eebbeb.jpg 05f5d0a8-417c-4c1a-973e-8ee7446a4b8b.jpg 50160b02-6f81-445f-9440-9af226813a2d.jpg d717e64c-ad09-4bcf-ba04-6d1e61359d94.jpg 41b20c96-c0b8-462e-9e58-edc6c94e0b10.jpg

Logitech x-230 9 pin problem . i need to manualy insert wires into pin holes.. So can anyone tell me the color and pin hole nunber to put right wire into


worked on this for 3 days but i finaly got it I had to open it an follow coper lines using datasheet, the connector is RS232 the pins are

1 = LED+
2 = IN R
3 = OUT R
4 = OUT L
5 = GND
6 = ON
7 = 5V
8 = GND
9 = IN L

so you have to put a swiths between pin 6 and 7

you should also put a potentiometer GND-IN-(AUDIO SOURCE)

and a led between pin 1 and GND

and that is it!

More info for you


The pot is a 50k ohm audio taper pot with an integrated switch. The shaft is called a "D" shaft and is used with knobs that have a set screw. The 3 pins are the for the resistance with the center pin being the wiper. The other two pins are for the on & off switch.

It's going to be hard to find the exact replacement without knowing the manufacturer of the pot. It looks like the one you have is soldered to a PC board and the pins have to be in the right spot on the new pot order to match up with the PC board.

What you can do is buy one with solder terminals. Rotate the pot so that the terminals are facing up and just solder wires from the terminals to the PC board. If the shaft is to long, you can cut it down with a hacksaw.

I am looking for sites for you to call. here's a few I found thus far:

My Teac Z-7000 will not record tapes


Hello,
some weeks ago I got this really impressive deck (Teac Z 7000) from a colleague, and found the same problem. I fixed it, and the fix is not too complicated. It´s the potentiometers that do fail. All pots are from the same manufacturer (Alps) and construction. The problem is that the wisher is broken away from the holding plastic and will loose contact completely. You can check that with a normal ohmmeter: You´ll find the total resistance over the outer terminals but endless resistance from one of the outer terminals to the middle wisher contact. The values are: 100 kOhm linear for each of the upper left pots (fader,space), 2x22kOhm pos.log. for the lower left pot (phone volume). So, what does a broken wisher at the "fade in" pot do? The Recorder "thinks" that You selected an "endless" fade in time, and the result is : no record level. You can do an easy "quick and dirty" fix just to see if that´s the problem: Hold- or better solder- a say 47kOhm resistor in parallel to the conducted potentiometer terminals and try to record.
4 of 5 pots have been defective in my deck, and I´ve replaced them with standard types from my local electronic supplier (Conrad electronic, has a shop in Frankfurt/Main). Well, the new parts didn´t fit perfectly, I used a file to get them in (not visible from outside). Also I lost the possibility of pushing the knobs in and out, but that is not a really problem.
I assume this fix might also help owners of the Teac Z-6000 and Z-5000, which- most probably- use the same type of potentiometers.
