I am not an electronic wizz kid like most of you guys, so here goes.

As I put together and layout this New Power Board that will be driven by the New OzControl Board with that new 8010 chip, I have slight issues and questions about particular components I have found on the Old 8kW -15kW PJ Board.

Number 1................

Firstly The Fet gates resistors will be 20k 0.6w metal film and 5r6, with a signal diode 4148, (anode towards gate) in parallel with the 5r6.

As I move things about to get those extra 48 holes, signal diodes, in the New board, I am also going to replace the old PJ 2W metal film 47r resistor, 4 per board, with a 2W 5r6, this just feeds to that 100n disc capacitor and not a gate. OKAY?
  I presume that a parallel signal diode will not be required on this particular 2Wresistor.?

Capacitor recognition please.....

Number 2......

The muddy brown/red thing has very faint 106J and 250v on it. It is 16mm wide 28.3mm long & 22.5mm high.
What is it please, so I may buy some more. ?
 NB, in the previous post photo it is lurking in situ.

Number 3.......

Capacitors again. What are these please?

They go to earth/ground and are 14mm diameter.

Clokman, here you can find a reference for the red muddy capacitor

Clockman, the blue ones are ceramic disc capacitors 103M, you can use same table to find the values, or you can use this http://grathio.com/assets/capacitor_tags.pdf

Thank you Eduardo, there good.

Awaiting PCB software for Gerber File creation, so I can have 20 boards made by these folk, they can do double copper thickness....    http://www.shenzhen2u.com/PCB   

The individual homemaking individual Power Board masks are all done, the required Board track changes and incorporated fast switching diodes, and component changes to match the new 8010....36 OzControl Board.
