自己绕吧..
5kV的话....绕起来不容易..

特斯拉线圈还是比较好绕的，最重要的就是小心击穿！

所以，我建议用一个塑料管，外面用细导线密绕，可以先在塑料管上贴一些双面胶带，就很好绕了。一定只绕一层，而且要均匀密绕，这样圈与圈的压差就小了。之后一端（管子下面的）接地，上面的就是电极了。

如果要绕多层就困难了，层和层的绝缘是个大问题，需要垫足够绝缘强度的绝缘层，而且最好整个浸在变压器油了，业余制作就困难了。



初级可以用一个磁棒或铁心，棒状，上绕初级，放于塑料管中心即可。

可以先输出1000V再倍压整流，去网上搜索一下就出来了

直接绕个新的不会很难,用大铁芯做小功率,之后次级每层绝缘应该就没问题了.改造比较麻烦,因为功率匹配的铁心窗口容积有限,无法加入足够的绝缘层,易发生线间击穿.
另外请务必注意安全,大功率的工频高压能让你直接和特斯拉大爷喝咖啡去,记住,在高压变压器面前你犯的第一次错误就是你最后一次错误.

High Voltage measurement
Let's handle High Voltage
You sometimes may get the impression that I don't take high voltage lethality serious. Let me seriously assure that I don't screw around when it comes to lethal high voltages. It is deadly stuff and I don't "play" with it or demonstrate bravery to guest.

You will see a few references to high voltage measurements, such as AC plate transformer secondary volts and rectified/filtered B+ DC voltages. How do I do it? I do it the professional and safe way. First I don't demonstrate this to anyone, no distractions - my full attention and concentration.

Master switch off, I clean off the bench. Nothing but the amplifier or device and the actual equipment to be utilized. Usually just the 10 mega ohm input digital volt meter, Fluke 40 KV high voltage probe properly plugged into the meter and ground clip attached to equipment chassis ground. I then run through, in my mind, exactly where I am going to measure voltage with the probe and make a note on a pad off to my right. I note whether the voltage is AC or DC and what voltage or range to expect. After I am clear and focused on what I am about to do, I set the meter for voltage type, slip the fresh thick leather welding glove on to my right hand and with left hand in my pocket, I pick up the high voltage probe and carefully touch the probe tip to the connector, terminal or spot for measurement and read the voltage in decimal kilovolts on the meter.

I lay the probe over by the note pad, remove the glove and note the voltage. Then I repeat for next measurement. After last measurement, I turn the master switch off an go do something else while voltage and energy bleeds off.

Oh yea, a while back I got a grade five surprise. The scale, important upper numbers  - -  

5 getting the shock of your life and scared, almost to death, overcome with self stupidity .
6 as above and being holed in several places.
7 all of the above and knocked on your ass.
8 all of the above and you couldn't breathe and thought you were dead.
9 all of the above and hospitalized, people trying to keep you alive
10 - - - - - - - - - - - SK.

HAM总有SK（Silent Key）的一天，但我绝对不希望因为自己愚蠢的过失提前参拜马可尼老人家……

呵呵，高压的确很危险，但是如果能够很好的限制电流，就能够避免对大多数的危险了。
