Tektronix455, high voltage transformer
<< < (3/3)
David Hess:
The 455 power supply section should be identical to the more common 465M.
jonpaul:
Doban good work on the transformer spec sheet. You can then test the part if removed from the PCB.

But just resistance tests on the windings.

Most issues are inside the HV insulation and reveal only when running.

Unfortunately without the manufacturer core, gap size, imprégnant  and bobbin part numbers, you cannot rebuild it.

But if its dead you can depot/remove varnish and ty ro reuse the cors and bobbin.

Wire type, insulation and build/lay is important.

Does anyone know what I circled in red means? Thank you.

Number of turns and wire size, for each winding. What a great diagram!
