Default Re: Sony SL-HF950 expert needed

Hi Kevin,

Many thanks for the update. I have been informed by a reputable electronics supplier that these are not fusibile resistors but are Cement WireWound resistors, is this correct?

Also in terms of the transistors, they don't appear to be mounted on any thermal paste or compound but a rubber membrane which then bolts onto the metal plate. I can pull the transistor away from this grey membrane with my finger, there is absolutely no paste anywhere to be seen.

However, inside the metal box there is a very thin layer of paste which seems to have dried out. This is where the back of the metal plate from the transistors bolt onto. I guess it is this paste you are referring to ? If so, could I renew this with thermal paste from CPU's?

Many thanks
