Re: Tek 576 Curve Tracer HV Transformer winding
Chuck is the 576 core the same as the 535, 545, and 585? I don't recall offtoggle quoted messageShow quoted text
If so, there seems to be someone who scrapped a large number of scopes on
the bay and is selling the HV supply assemblies for about $24 in the USA
Searched "Tektronix transformer", sort by best match, but then look for the
worst match at the bottom.
So all is not lost in any case for a 576

Just remember the ferrite is a ceramic mixture,
so it was once heated much hotter than your oven
will ever go.
Good gloves so you don't burn yourself, don't worry
about the winding. Soak it in the oven, and then
remove it and with two hands give the top half and
the bottom half a twist, like you were removing a
If that doesn't work, up the temperature.
If you break it, don't cry. A drop of thin crazy
glue, and carefully aligning it back together, and
you will never know you did it... electrically.
A dry trial fit is a good idea, and a little compressed
air to remove any extra bits of ferrite sand that may
be in the way of a good fit.
John,about this. I have not done any "practice" since I don't have anything to
practice on. I guess this is my "practice" piece? I'm going to cut the
rest of the coil off and then go from there. I appreciate Chuck's offer,
but I really feel the need to try to do this on my own. I may break the
core, I may be successful or, in the end, I may give up and send it to
Chuck. If I break these ferrite cores, I may come crying to Chuck or others
for a replacement set. I appreciate your advice and insight. One way or
the other, I will get this thing fixed. It is a shame that one stupid part
has disabled an otherwise functioning instrument. Before it "cuts off", it
