No, that's not the little ferrite transformer who is defective but the big one....A short circuit in the High voltage coil of the transformer.
Here a picture of the transformer with the HV coil removed and auxiliary HV board added.
Hi all,
sorry being off-line a while, we had some building going on in the house...
Anyway, I managed to re-use the little ferrite transformer, the one that drives the Basis of the two BD237 transistors. (not in the picture, I put it on a small plug-in board)
If I temporarily replace the fuse with some power resistors the power supply "sort of" tries to work, generating lower voltages, but as soon as I increase the primary current by reducing the temporary series resistor the BD237's will immediately die again.
So it looks like I do have a transformer problem, but........ Mine is different?!?
I now understand that some repairs were done by removing the HV winding and add a separate HV supply?
In my situation, the transformer is in a sealed, plastic box, so this is a complete No-Go?
See the attached picture of my Power Supply.
Un saludo,
