Need help identifying components from a diagram

zYx · 10 Dec 2012 at 19:47

Hello,

I just have question.
What mean 10K - 10K marks on the diagram below?

Resistors?

According to the picture below, these don't look like resistors to me or am I missing something?

This diagram shows how to build a ground loom isolator for car audio. I'm not entirely sure what components I need according to the above.

If someone could guide me to maplin for the corrects parts I would be grateful.

Cheers.

Primary Impedance: 10 kOhms
Secondary Impedance: 10 kOhms

The component list and part numbers can be obtained from the original source:

they're toasters

You need 10 karat of pure gold.

That? and what are these vertical lines between resistors?

isolating transformers , impedance or # of turns

Brown, black, orange and at least silver, preferably gold

Nope

Ah I see, but it has 6 pins, how do I connect it?

ref datasheet

you are looking at schematic A, 6 pins

your diagram is missing two dots to identify the start of winding, so assume at dot at the top, on both sides

so on LHS, input into pin 1, ground on pin 3
on RHS, output on pin 4, ground on pin 6

I'd double check this with Dr Em, it's his area really

Shame the estimated delivery is February 2013

Ah, awkward.

I was looking on ebay for equivalents but there is nothing really, just a bunch of 600ohm line transformers and almost no 1:1 types.

Frequency response quoted is a bit poor for some of them too, something to keep an eye on when looking for equivalents.

Ask around on the DIY audio forums, someone may have already researched something similar

Apparently, this is what I need and this one being the cheapest with 3.5mm jack.

"Frequency Response:: 20-30kHz"

LOL

Yes it's the same idea, quality is going to be vastly different thought,
they haven't quoted the impedance so you've no idea what effect it is going to have on your system.
It might roll off the upper frequencies so it sounds like a telephone for all you know.
