dent and scratches on the metal

Broken plastic ribs, sorry but you have to click on the picture to see more

de-soldering of components that could be the cause inhere, the ROE capacitor and the diodes. 

Ready for testing at my work, sorry picture made by my old Nokia.

A handy for de-soldering a woven lead made by copper.

Sorry I have to leave now, but I will publish more and rewrite the postings done here.

I only have experience using this woven copper lead. It does work great BTW.

Problem: blowout  fuse F3, replacement fuse was also blown out.

Noticing:  hard plop sound on the speakers when connecting the Beomaster to the main power 230Volt supply. Burn spot on the rectifier print board near fuse F3. 

First action: disconnect every plug on the amplifier print board, remove fuse F2 and F4 [shut down 33 volt system], changing from 220volt to 240Volt on the primary, see picture here.  NO EFFECTS

Next action: The suspected burned print board from the rectifier: removal of the Diodes D10, DD17, D19, D27 and the ROE capacitor. These will be tested at my work, changed by new ones, only the 4700uF ROE seems to be not available anymore, so this will be exchanged by the Panasonic FC.

Here a picture with the burn spot on the print board.Maybe I also remove the white capacitors [C5 & C37]  seeing that burn spot, lot of heat going from diode to the print board. The new diodes of the rectifier will be soldered 10mm above the printboard to give the diodes more cooling.
