 8th August 2017, 03:28 PM #1 jerrylong   diyAudio Member   Join Date: Dec 2008 Audio Note M10 Clone I have bought a CNC winding machine, and try to use it to copy the AN M10 output transformer IMG_0454.JPG

I will post a photo when next back in my workshop. It uses a counter from a pre 1960s gas meter on a short piece of bowden cable to the winder. If you unwind the transformer, measure the wire gauge and count the turns, that is all you need to know. Laminations are widely available and off you go. Happy days. __________________ Support for Fender, Marshall and all Valve Equipment; Audio Innovations, Audiorama FU29, Quad and Leak. www.jonsnell.co.uk
 8th August 2017, 03:59 PM #3 jerrylong   diyAudio Member   Join Date: Dec 2008 First of all is confirm the turn ratio. M10(old version) used Tran027 for the output transformer and the turn ration is 33:1. But I doubt about it. Two reason:1, if it is 33:1 is correct, second impedance is 600R, the prime impedance will be 600*(33:1)^2=650K?;2, the output stage is 5687 parallel, the output impedance will less than 6.4K(the typical operation condition of 5687 ) IMG_0456.GIF
 8th August 2017, 04:00 PM #4 jerrylong   diyAudio Member   Join Date: Dec 2008 So I think 3.3:1 will be alright?

Opt primary impedance for audionote M10 phono pre

 8th August 2017, 04:56 PM #8 audiowize   diyAudio Member   Join Date: Aug 2005 Location: Seattle A paralleled 5687 is pretty flexible and would work OK with a lower step-down ratio. 15K:600 is a super common transformer that will still present a very high load to the 5687's. Heck, if you choke load those 5687's and use parallel feed you could really have some options for the OPT.

33 = n^2, so it's 5.744:1.
