    Would the electronics experts please sanity check my assumptions.

    This, to my failing eyes is a 0.0047uF cap:

    This is a 0.047uF cap:

    1A862700-6287-48E9-B880-9C5AA9A3CB4F.png

    I've got an eye test next month but the only way I can read the values is taking a photograph and expanding it like these attachments.

    The resistors are easy as I keep them in the packets in with the values written on the but being colour blind, I have ZERO chance of determining the values without help.

    Below this post I add a selection of other caps I can't read the values of. If you're feeling charitable and have the skills time and inclination, maybe you can verify the values.

    Thanks in advance you lovely people. :)

    These two came with genuine Fender No-load Tone and Volume pots.

    Their website says they are 0.022mf 250V capacitors but one appears to be a 0.01mf 250V capacitor. Is it just me or am I reading it incorrectly?

    I always check values with my multimeter before installing in any equipment. My eyes aint so good either. Sometimes those caps and resistors can be mislabeled, a good meter is fool-proof.

    They are both the same value - 0.047uF. One is 200V, the other 100V. The letter in the 4th position indicates tolerance, and has nothing to do with the value. At least that is how I read them.

    I cannot comment on your sanity.

    The first 2 caps are the same value, 0.047uF (473), the next one is 0.022uF (223) and the last one is 0.1uF (104)

    I'm confused

    Is that a typo?

    Does the voltage matter?

    Yes, as tone caps. I should have made that clear.

    Thanks. :)

    I tend to use 0.022uF as tone control caps on my single coil guitars: I find it gives me more control over the roll off since I rarely use the fully off position. In fact I even used a 500K and 0.022uF on a Strat built recently and that seems to have worked really well ('65 Pure Vintage pickups on that one).

    I think typical Tele values would be 250K and 0.047uF though, but something to bare in mind as even when they are fully up (ie at '10') the pot and cap have an effect on the overall tone as can be heard on an Esquire when you go from middle position to 'bridge' as that (usually) bypasses the tone pot all together and gives an extra bit of bite to the sound.

    I know what you mean about reading the values as I'm due another eye test soon and my reading glasses aren't great, so I just stick the capacitor right in front of my bare eye and can just about read them. :D:oops:

    EDIT: Most meters won't measure capacitance, unless you've got a really fancy one. We used to have a 'Wayne Kerr'* bridge meter at a firm I worked at years ago and that could measure capacitance very accurately.

    * Say it out loud and you'll realise why I still remember the name. ;)

    Yes, I've discovered I don't have one of those meters! :lol:

    A big thanks to everyone who contributed to this thread.

    The comments and advice has been enormously helpful and has given me the knowledge and confidence to ordered the correct caps. :)

    I got a LCR multimeter last year for cheap on Ebay. I checked it, and its pretty accurate. $25 I think?
