270mac
 

Hi I have this little brown component that I think is a capacitor, if it is what would be a suitable replacement thanks

Re: 270mac
 

Is it dark brown or light brown?

Picture?

Does it read open circuit, short circuit or about 270 ohms with an ohmmeter?

What part of a circuit is it from?

Re: 270mac
 

Maybe a silly question, but if you don't know whether it's a capacitor, how do you know it needs replacement?

Re: 270mac
 

Here it is. The reason I need to replace it is because I have had to replace the vol pot, and I cut this component off and its too short to reconnect, so I thought I'd just fit a new one. Its from a bush SRP31C

Re: 270mac
 

It's a ceramic capacitor. But, if it's as it is now, stick a bit of TC wire on the end and it'll probably be fine. Not sure about that 100k though!

Or that 'orrible black and red Plessey....

Re: 270mac
 

or that yellow Plessey electrolytic!
Its probably a 270pF ceramic capacitor as ,ucien has said, and I agree with him that a bit of solid core wire would solder onto the end. You might even get away with the same trick on the 100k underneath but for the cost of a new one I think i'd replace that.

beat me to it turret!

Re: 270mac
 

It is indeed a 270pF capacitor.

Thank you very much for all your help, I know there's a lot more to do to this amp, but you have helped me to start it , which allways seems to be the hardest part
