Hi Guys
silly question but can some show me how to wire this please

[IanB]

The diagram seems clear. What aspect of it is causing a problem?

[tautech]

RV means variable resistor eg pot or preset etc.
This configuration is not uncommon with the wiper and one end on the pot "commoned".

[Jbliss]

so the pot is just is series and the common is connected to the centre pin ??

[tec5c]

A potentiometer/variable resistor will have a minimum of 3 pins. Across two of them will be the maximum resistance value, while the third pin is used as a wiper (variable resistance pin). A quick check with a multimeter (or datasheet if you have access) will tell you which pin is the wiper. Once you know which pin is what, wiring it up should then be quite trivial.

Do you have a specific component you are trying to wire up? If so, please post a photo of it or link to a similar one.

so the pot is just is series and the common is connected to the centre pin ??

Yes, basically. The center pin (wiper) is connected to one of the outer pins and to common (the schematic uses the chassis symbol - check that this is actually meant and is a safe thing to do).

Which outer pin you connect to depends on which direction you want to turn the pot to increase or decrease resistance.

So like this ??

So like this ??

how you've got it is shorting the power to the chassis. - not good.

[Jbliss]

its a common 0v

[Delta]

So like this ??

That will work great.  At ensuring zero output...

[Jbliss]

Can someone draw the correct way Please

try

[SL4P]

a potential problem as drawn...
at one end of travel, the high side will be 0R to chassis !

[Jbliss]

Heres is the full Preamp Circuit

[SL4P]

all good.
use JouleThief's wiring diagram.
Comment: using arbitrary arrows or symbols can suggest signal conditions that aren't actually present in the actual circuit.  The full schematic tells us what/how the VR is being used in the circuit, so how it is wired up becomes apparent.

Please always post full schematics, instead of tiny snapshots.  Also, take a step back and look at what you've drawn.  Surely after 10secs of looking at your sketch you would see that that arrangement couldn't possibly do anything...

[Jbliss]

Yeah sorry realised as soon as i posted it

[fleuroman]

RV1 is extending the voltage divider created by R1 and R4, a simple volume control, so it will work with either pin 1 or pin 3 of RV1 grounded, it might just work backwards to how you want it to work, the contacts/pins on RV1 should be numbered 1, 2 and 3, not 1, nothing and 1 as in the diagram

Hence why I assumed power on OP's last schematic.
