Hi All
I have taken a cs 69 out of one strat and put it in another but it does not sound the same and guitar is same construction i.e. alder, rosewood fingerboard . I know that the cap is different so would like to get another the same value as old guitar the spec is as follows;

ic msr 104k
250v S 543

I think the last number is 3 but it is not very clear. I have looked around but cannot find out what the last three numbers refer to. Does anybody know , also where to buy in UK.

Many Thanks
Mike F

104 k mean 0.1 micro farad at 250 volts

IC is Ilinois capacitor. Very cheap IMO.

543 probably mean 2005 or 1995 or ......, 43th week

250 volts is very high voltage for a guitar, don't need that but won't change sound . This probably standard value. Higher voltage = bigger size too.

I like Mallory or Sprague / SBE " Orange drop " capacitor. Easy available in North America. In UK , I see this on Google;

Hot Rox UK

Or All Parts UK

Hi Stratele52
Thanks very much for that you have been a great help.Something puzzles me .You said that 250v was a bit high, but the orange drops are 600v, I realise the voltage does not affect the tone but seems very high.

Thanks
Mike

These are often standard voltage but you can find 400 volts also . Use any voltage , this do not change sound / tone . More voltage = bigger in size = cost more.

These are "high " for guitar because guitar do not have more 0.030 volts , less than 1 volts. You don't need 600 volts but manufacturer don't make 1 volts capacitor. Go ahead and enjoy.

Mike, just to check, are the pots the same in both guitars? Even if the caps are the same value, the tone might be a little different if the pots are not also the same, particularly when the pot is opened up - a single coil with a 500k pot on 6 or 7 might sound more trebly than it would with a 250k pot wide open, for example.

Also bear in mind that even if the pots are stamped with the same value, there can be pretty wide tolerances in manufacture (250k pots often measure anywhere between 200k and 300k) which might still influence the sound. By starting out with pots in the new guitar stamped to the same value as in the guitar you took the '69 from, you'll at least be in the right ball park though.

All single coil guitar must have 250 K pot as standard.

I wouldn't entirely disagree - all I was suggesting was that the guitar Mike swapped the pickup into might have different pot values.

You are right , a good check on the pot value is a must.

OK guys here is the position , ive had them both apart today and all pots are cts 250k . Both caps are the same 0.1uf.
One was labeled icmsr 104k 250v
the other ic 1k 250s

same physical size , the same ?


I am assuming they are the same ,so think the problem may lay somewhere else so am staring a new thread called

CS 69 different scratchplates give different tone?

Many Thanks
Mike

just a thought.....
104k and 1k are not the same values. 1k it probably is not but did you read the cap values correctly :D

No two wooden constructed guitars will ever sound identical.

Does not matter if you think everything is the same. It really is not. All those wood pieces have different densities. Bridge, saddles, strings, nuts, and turners are all just a bit different and adjusted a bit different also. All effect the resonant frequency to make a difference.

Adds to the saying - No two Strats sound the same.
