    I'm afraid I didn't pick up any Finnish as a kid, I could be persuaded that my post was a bit hasty.  People are excited about building a 'new' kind of pickup, does hyper analysis of who had what idea first help them physically make a pickup?

    I suspect that most people are more interested in building a pickup, but, I can appreciate your desire to insure that credit is given where it's due.

    That's weird, Moritz. Did you somehow get blocked on that discussion? Ask Dan Sleep to look into it, as he is one of the site admins.

    All I can say to this is that most of us are lazy. It takes time to go back and verify things one thinks one sees or remembers, and not everyone may be as scrupulous as that. However, Wayfinder did finally go back and look, and changed his opinion.

    Hi Moritz, sadly, it doesn't surprise me, the problem with those threads is the person who initiates them can remove them at any time, taking everyone elses input with them, not the first time it's happenned, it's a pity as there was some good stuff on there, some i wanted to reference again at some time. I try not to get paranoid about these things, but there seems to be a pattern.

    If you want to know the total output impedance of your current transformer pickup without an LCR meter, just assume that the shorted primary of the CSE-187L current transformer is 80 Ohms, then just add the resistance of the added string loop wire to get the new output impedance with the string loop. Here is an example. Adding a 6 inch hairpin loop to the CSE-187L adds 105 micro ohms per inch for a total of 630 micro ohms. Now multiply 630 micro ohms by 250,000 or 500 squared (turns ratio squared) to get 157.5 ohms. Add this to the 80 ohms of the shorted primary to get 237.5 ohms as the new output impedance.

    Just using this method you can calculate the output impedance of your current transformer pickup and not need an LCR meter.

    If you are feeding an XLR mic input that has an actual input impedance of 2400 ohms, then you want to target the output impedance of your cuttent transformer pickup to be about one tenth of the actual XLR mic input impedance of about 240 ohms.

    This technique just allows you to predict the outcome of using various string loop wire gauges and lengths.

    I hope this helps.

    It was probably intended to say something like measured electrical output. That is the problem with an ipad tablet touch screen keyboard. Sorry for the confusion.
