OK first of all thanks for your answers, now OK, if you look to the sides of that hyppefast diode you mention theres a silhouette of the transistors that were there clearly bigger than than that, I remember the components had 3 legs.It is clearly marked on the PCB D23 which is a diode and the component markings indicate BY-C15 which is a Hyppefast power diode. extension://nhppiemcomgngbgdeffdgkhnkjlgpcdi/data/pdf.js/web/viewer.html?file=http%3A%2F%2Fpdf.datasheetcatalog.com%2Fdatasheet%2FNXP_Semiconductors%2FBYC15-600.pdf
The PCB markings in the other spots are for transistors. Without them or a schematic specifying them you are outta luck.
They have a TO247 case & could be FETs, type SPW20N60C3 20.7A 650V Check if the device driving them is a transformer, in which case they could be transistors, of in IC design to drive FETs. the datasheet of the device will tell you.
