Re: Difficulty winding and installing transformer T1 #qcx


 

Agree with Ted. Indeed, take you time unwinding it and, when done, I take two pairs of pliers and give it a light stretch, which seems to make it easier to wind.

Hi Im

I've not long since built my QCX40 and T1 was my first ever torroid. It is tricky but I think what has happened in your case is that you haven't "unwound" the wire.
I know it sounds mad but it needs to be unfurled from how it was packed in a straight line, otherwise you will get the kinks I think you are referring to.
I believe you will now not have enough wire but any of the same gauge or even less will do (so I believe). The gauge supplied for the QCX40 does just fit, though it is tight!,
Just make sure that the wire you order has enamel that can be burned off with a solder blob.?I bought some that wasn't for my ZM-2 AMU and it took an age to remove the enamel, used a fine rubbing paper in the end. I got mine next day from ebay. (UK)
Good luck Im, just have patience - this is the trickiest part of the build by far.
