Using a Mains Bulb Tester will indicate as soon as a miswired transformer is powered ON.
Instant indication and protection to prevent damage to the transformer.

And what does this exactly mean?the trannie is used on 230v mains so primaries in series, ie black and white together
Please *draw* your wiring, even if it looks unimportant to you.
Not from memory, but what you see.
If both primary halves are coded identically, let's say the black wire at the beginning and the white one at the end, he's done it right.

I also suspect somehow a misconnected primary (because it happened to me, leading to destroying an otherwise perfectly functioning toroid). They have to be connected in series, ex: two Black-White pairs like this: 1Black-1White connected to 2Black-2White. 1Black and 2White connect then to 220V. Please separate the coils, and with a multimeter identify the pair 1 and 2. It is sometimes easy to connect the 2Black to 2White creating a shorted secondary.
A picture would help, nowadays it's very easy to provide one so that we understand what you're dealing with.
Shorted secondaries can also happen

Hi,
A lot of disucssion on the wiring of the primary i see. No need, that one is easy. Datasheet is here: https://www.ringkerntrafo.nl/shop/h...edingstrafo-voor-buizenversterkers-101va.html
Link is at the bottom
I've got 230VAC supplied. Thus tying the primaries in series by connecting black and white is as required.

Jazz, I would be interested to know, now that it's working ok, whether the fuse blows if you short the top mounting plate to the bolt.
oh and a piccie. The ht caps on the left are temporary. Waiting for the desired ones to arrive. These are just used for testing and measurement but rated adequately.
Before discussing further, remember it works perfectly fine now. I did find a wiring error but that's solved. Maybe that in combination with the mounting at first instance caused the fuse to blow but it was isolating the top mounting plate from the center bolt that stopped the fuse from blowing.

Take AndrewT's good advice. Lamp Limiter.
IF you can still find 100W *incandescent* (or "halogen") lamps, they will be cheaper than a pack of fuses, and work over and over.

How do you know?If both primary halves are coded identically, let's say the black wire at the beginning and the white one at the end, he's done it right.

Let´s expect the actual OP answer.
You are assuming something I am not certain was done that way, pictures work better than words in this case.
And please reread his answer, he did not say what you are saying.
EDIT: just downloaded the datasheet,
does not apply, there are Brown and Pink wires which weren´t even *mentioned* in earlier posts, confirming once more that OP descrription was vague, incomplete and that again "an image is worth 1000 words" 🙂both primary halves are coded identically

The short is only going to be created if the top mounting plate or bolt is also making contact with the chassis at the top end
I had been struggling to understand what people meant by a shorted turn and your pic perfectly showed it to me. Know I finally understand. Thanks you!!
