Does anyone know where I can get a replacement transformer for a Weller 1002?

Dear forum
My Samsung fridge died from a fault on the mainline and the transformer (https://www.hqelektronika.hu/hu/halo...-w8-da2600009k) died.
No voltage on the secondary, measuring resistance shows open circuit. I concluded a blown fuse which is deep inside the transformer, I don't think I can disassemble it to replace the fuse.
The second problem is that I cannot find an original replacement part anywhere or even If I do it's pretty expensive.
My question is: Can I replace this transformer with a generic 230V to 17V one? The output has 4... -
Hello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow... -
Hi guys,
I have a dead coffee machine, and it seems that the culprit (no 1, at least) is a dead trafo - primary coil seems to be blown open (type shown on the picture below).
Now, I'm unable to find direct replacement anywhere on ebay or aliexpress, and all similar that I' was able to find are rated too low (<1A).
If someone knows a shop to buy replacement (EU/CH), that would of course be my 1st option.
My other ideas:
- to buy 220/20Vac trafo with 30VA, and to "manually" create secondary 12V output just via resistor
- to buy... -
Got a Sony STR-DE697 with a bad power transformer (1-435-281-11). This will be my second receiver with a bad transformer; the first I was able to find a direct replacement off ebay. With this one, nothing has been found except for an old ebay listing for the sub board itself.
Tried to find a service manual to determine the transformer's specs but to no avail. Tried similar models with the same model transformer but no go.
So....
1) How does one determine a transformer's specs (input, output) if there is no information about it available? Are there... -
Hello!
I'm looking at an original Xbox PSU: Foxlink ftps-0002 rev. B. The 12 V output is too low, and the 5 V output is too (?) high. Unfortunately I don't have an oscilloscope but only a DMM for diagnosis.
Measured voltages with no load:
After rectifier diodes
12V: 6.17 V
5V: 5.67 V
Secondary transformer pins AC measurement (really don't know if this says anything)
12V: 2-2.5 V
5V: 1.04 V
I also have another (working) Xbox psu from Delta. The same measures there, in order, being: 10.79,...
