I submit for you some recent winds that all fall into the category of high current.
First up a pair of 120mhy 2.5A amorphous choke input chokes followed by a pair of 40mhy 49% nickel chokes for a LCLC balanced field coil supply.
Since computer servers only need one supply, here is a 40mhy 5A amorphous and 10mhy 5A 49% nickel set for a LCLC linear supply for a music server.
The next six are 180mhy 1.25A chokes for use in the filaments of some 801 / 841 projects.
All of the tubes are for reference and for scale, here is an autoformer compared to the (wonderful) tube in the above picture.
Quad QA12/P Amplifier - This is pretty close to Quads first amplifier. I got to put my hands on one of these once very cool early British amplifiers. http://www.itishifi.com
