BigOne.Lt Posted June 3, 2011 Report Share Posted June 3, 2011 Hi during search on your site i found an interesting project (http://www.electronics-lab.com/projects/audio/014/index.html) but i have several questions1. Does the 4K7, 5K6 mean 4700oms(4,7K oms), 5600oms(5,6K oms) 2. Does someone have a pcb layout of this project, if yes than plz send it to me ([email protected])If no one has pcb layout then plz check mine (it is my first try to work with "eagle" and create a pcb layout also i am quite new in electronics so i dont trust myself) http://bigonelt.imgur.com/elektronika#Kf1yIThanks for everythingP.S sory for my bad english Quote Link to comment Share on other sites More sharing options...
Hero999 Posted June 4, 2011 Report Share Posted June 4, 2011 1) Yes.2) Good, you couldn't find one so you did your own. All I can say is, providing you've used the correct footprints and allowed enough room on the PCB, there shouldn't be a problem. Please post the Eagle files zipped up.

BigOne.Lt Posted June 5, 2011 Author Report Share Posted June 5, 2011 So here is the zip :)stiprekas.zip Quote Link to comment Share on other sites More sharing options...
Hero999 Posted June 6, 2011 Report Share Posted June 6, 2011 How do you intend to produce the board?Are you going to be using the silk screen? If so, it's a total mess, the text overlaps the parts. If not, this doesn't matter, don't worry about it.There are some acid traps created by 90o angles but you've used such a thick trace width, it shouldn't matter.

BigOne.Lt Posted June 7, 2011 Author Report Share Posted June 7, 2011 Hi. I am thinkig to produce the board in some sort of this way http://www.riccibitti.com/pcb/pcb.htmI don't think that I'll use silk screen it is too difical to me for now. It is my first pcb so i am woryed about spacing between the traces aren't they too small? Quote Link to comment Share on other sites More sharing options...
BigOne.Lt Posted June 19, 2011 Author Report Share Posted June 19, 2011 Ya and another stupid question which pot should i use linear or logorithmical and what are their differences??P.ssory for my spelling becouse i am writing from my mobile XD Quote Link to comment Share on other sites More sharing options...
audioguru Posted June 20, 2011 Report Share Posted June 20, 2011 which pot should i use linear or logorithmic and what are their differences??When the pots are centered you want no boost or cut at bass and treble so linear pots must be used.Logarithmic pots are only used for volume controls because our hearing's response to loudness is logarithmic."TREMBLE" hee, hee.

BigOne.Lt Posted June 20, 2011 Author Report Share Posted June 20, 2011 Thanks for help!!! Tomorrow i'll buy all stuff and i hope it'll work XD Quote Link to comment Share on other sites More sharing options...
BigOne.Lt Posted June 28, 2011 Author Report Share Posted June 28, 2011 Finally got all parts and question like always. One of my potenciometers is A100k and another is B100k so the question is: is there any differences between them?? Can i use them for this project??

audioguru Posted June 28, 2011 Report Share Posted June 28, 2011 I think an "A" pot is logarithmic and can be used for a volume control. A "B" pot is linear and is used for tone controls.Simply turn the pot to halfway rotation and measure the Ohms from one end to the middle slider terminal. A linear pot will measure half the total resistance of the pot and a logarithmic pot will measure 1/10th to 1/20th or 9/10ths to 19/20ths.
