I have the transformer but do not know exactly where I laid it. When I find it I will put it together in a box to that I can plug the ipod into then plug it into the AM-1780.

Yes, but some have said the impedance input on the audio input side is more matched for the Ipod out put.

I have made progress, sort of. I got the transformer but have yet to build up the system or make my ANR 2298 box. Too much else to work on. the problem is the impedance is not matched so it is not as easy as connecting ear bud cord to the audio inputs.

Thanks for the input guys. It is too cold to work on it right now but I am trying to get my ducks in a row before spring. I will report back with the results. I also need to modify a 2298 to power my bose ANR headset.

I found out that someone measured the impedance at the headphone jack on the ipod as being 5 ohm. I also found the attached plans for a FET impedance transformer. It looks like the input and output is variable by the values of a couple of the resistors. Anyone see any problem with this circuit...

Question for any electronics guys out there. I read Bjorn's article in MVM about his adding CB audio to his vic-1 input to listen to the CB on through the intercom. He used an audio impedance transformer to connect the 8 ohm speaker output from the CB to the 600 ohm input of the vic-1. My...
