Re: Foot pedal re-stringing diagram / advice please
This is a soviet guitar prefix, the arrow indicates the resistor that you need to check on your 10 kOhm board and check VT4Attached Files -

Re: Foot pedal re-stringing diagram / advice please
I would get the model number in Cyrillic and search yandex for it. Or even similar models use the same string/pulley system. Maybe post here:

The hard part is getting 270° rotation between full up and down of the pedal and I can't see the pedal pulley.
Your R16 looks burnt- but it's more like glue is on it. 10k needs a lot of voltage to cook. A Q-tip and IPA can clean things up on the board.Comment

Great RJ thanks
Looks like string loops round once over the pot wheel .
Should be able to sort it now .Comment

Re: Foot pedal re-stringing diagram / advice please
Have managed to string it .
Don't seem to have the full range of movement from the pot , but i doubt that was ever the case .
Will test & report back .
Here's some pictures for now .Attached FilesComment

10K resistor mentioned by Skynet85 measuring good .Comment

OK, this is a long shot. I got this sewing machine cheap because it's end of line, ex-display, and had no pedal. The genuine pedal costs £60, while Ebay knock-offs go for around £15. So I went for the knock-off, it doesn't work, and I'm not sure whether it's the pedal or the sewing machine that has the problem.
Now this is an electronic machine, unlike the old fashioned sort where the pedal was a big resistor in series with the power to the motor. Here, the pedal is just (I think) a variable resistor fed with a 5 volt supply, and limited to a current of 5 milliamps. Assuming that... -
Hi All,
I obtained a schematic diagram for the above mixer but I am wondering if a block diagram exists as I am trying to fix a problem in the protection circuit which I find a little confusing using a circuit diagram only. In the good old days the workshop manuals always had a block diagram with a circuit discription. Very useful for fault finding.
The protection light is perminently on. The right sode has a -80DC on the feed to the speaker, hence the protection led on. I have removed all the O/P transistors which checked out OK. I tested all other transistors in circuit which seem... -
Hey all! I have this midi controller called a "Synthaxe" which is pretty rare. It was made around 1986 and the company only made about 100. I was told less than 25 still work today. Theres a guitar player I love that is known for using this and to play his material you basically need one of them because it does things no other midi-guitar controller can do. So since I got it, ive been trying to learn about it so I can extend its live as long as possible.
The one that I bought has 2 issues. One I'll cover another time but I think this one is easier and simpler to fix.... -
hello everyone, I'm looking for the wiring diagram of this led monitor.
the model is DHI-LM19-L200, but I think that any other diagram of a DAHUA monitor could be equivalent.
I really hope that among you someone can help me to repair this monitor, the screen is black, it doesn't seem like a backlight problem.
I see the presence of 12 volts, 5 volts, but without a diagram the repair is very difficult.
thanks to those who will answer12-10-2024, 04:37 PM -
I’d appreciate some very basic advice on CH341x programmers. I know this topic comes up from time to time, but stuff changes, so I hope a refresh is in order. In particular, I see some unexpected things happening with jumper positions.
[My plan is to learn to read and write 24CO2 EEPROMs via I2C. The first target is the one in my Uni-T clamp meter, but before tackling that I have some brand-new EEPROMs to practice on.]
I have two basic Chinese programmers. One is the blue board with a CH341A and two rows of pin headers. To my untrained eye it looks like all the others....
