Re: 270mac

Re: 270mac
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!

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. A. |

Re: 270mac
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
