so i searched the internet and saw that i need a preamp connected to a PA system if i dont have a real amp when playing live.. and i decided to make one since we already have a PA system.. i saw a preamp with tone and voluke controls but it' a bit complicated for me just look on this site please


http://www.circuitlab.org/2011/09/schematics-preamp-tone-control-circuit.html?m=1

so can you translate it into a perfboard layout which is so easy to understand or into a stripboard which is easy too..

so now that i have a new soldering iron i can make DIY projects again.

anyway pls help me it is urgent since we always play live every sunday..

Sometimes it's best to slow down... And take little baby steps vs diving right in head first...

Aiming for Sunday completion when you can't even read the schematic is very optimistic... Especially when the schematic you linked to has no values or part numbers to even start with...

Cocacola .... there is a component list :) down below the schematic on the main page (not the enlarged schematic page)

But regardless, I agree with you, its not going to get completed by Sunday

@ electronoobz ... you would be better off buying a ready build preamp module, its the only way you will have something ready in time for this event :)
You dont state what country you are in .... do you have tandy ? radio shack ? or somewhere like that that sells preamp modules ?

Hmm, when I clicked that link the first time I wasn't taken to that page, I was taken to the blow up page, interesting...

no i can read them but im confuse on some parts like on transistors.. im always confuse with it. and with potentiometers coz sometimes i thought it was a resistor..

im lived in philippines and there is no radio shack everybody talked about

Of course you can put this on a perfboard or a stripboard.
Is there something specific you want to ask?

Those arrows are going through resistors. They're potentiometers. Normally the arrow is shown going up to the resistor when used in this way. It is a bizarre mixed up symbol, but the meaning is obvious. The wire connected to the arrow is the wiper and is normally the centre of three connections.

Yes it's wired the same... Not all schematic pictures are going to be 100% identical there are minor variations in how people draw them... The direction of the arrow in can be used to indicate flow direction aka input or output, in this case or it could identify a specific type of potentiometer or variable resistor... But most likely (and in most cases) it just a generic symbol representation and it will differ between artist...
