Is there another type of Cap I can use instead of this one , difficult to get that value / type and pitch ?.
HiThat is an AC rated capacitor. You could use a higher voltage rating capacitor, or possibly one that is a bit more in capacitance value, possibly 39 or 47nF.
Based on your picture, there is no visible evidence that cap is bad. What makes you thing that it is?
How are you testing them?, and what do you mean by 'it tested the same as an electrolytic'?.
Certainly I wouldn't suspect that capacitor of causing a problem - but it's a fairly 'complicated' circuit (for a record player) as it's an early brush-less DC motor.
Assuming it's C12? (you didn't say) then it's in a very low voltage part of the circuit.
Thanks for your reply, I mean I done the same test on the Polyester Cap as I did on the Electrolyte one's ! ., not sure what you mean is it a C12 !.
The reference in the circuit (C12).
But what test?, and why are you concerned it tested the same?.
how long do you expect a 33nF capacitor to hold charge when connected to a 10Meg resistor? it will discharge in 100ms, so no surprise you don´t see the result you expect. You should test it with a meter that can measure capacitance and also ESR if possbile.
Bascially all multimeter have internal load resistance of 10Meg ohms, so when you connect your meter to enything you load the voltage you are measuring with that resistance. And in case of that tiny capacitance it discharges so quickly that you can´t even see the result.Thanks for your reply, not sure what you mean " Connected to a 10Meg resistor " .

I am getting a little confused here ( easily done !) .
Can I test the Polyester Cap using a Amprobe AM 500 Multimeter , if so how do I do that test , other than the way I have said I done it ! .
You can't really test capacitors with a multimeter - but you don't repair things by randomly trying to test components - I wouldn't have even looked at that 33nF.
Thanks again for your replies , if you have little knowledge like me, it is sometimes the only way for me to find out what the problem is by elimination ! .
