Hi Oz,

Just the pin 6 part "the pin 6 on the 8010 needs to be heated up, and pushed through the board so it is on the top of the mini board. This becomes the on/off pin, the other two pins on the control board are +5v and gnd, so use a spdt switch for on/off."

If I do this is that the same, I don't have room for pin sticking out the top in my case with the big heatsinks.

Thats the wrong pic as you know, this is the one you have in front of you



Every thing stays exactly the same except the pin 6 on the mini board goes nowhere ie pin95 does not connect to the bottom board.... it is isolated and goes to the on/off switch which is a double throw single pole.... so you can get rid of pin 6 on the mini, and connect a wire to it to the switch. The on/off pins 76 and 77 go to the switch, such that we connect either +5v or gnd to the pin 6 on the mini board. If you solder directly to the pin 6 ( 95) on the mini.

Here is a messy drawing of the changes, ie 95 only goes to the switch, the red tracks are erased by pushing the pin up through the board, or cutting it off and soldering a wire to it instead... ie isolated from everything except the switch pole.





The pink leads go from the 76 and 77 direct to the switch.

Clear as mud now?

Reason.... as original, pin 6 was turned on permanently, and I used the spare temp switch for on off... as I had issues with pin 6 previously ( I thought)..... but in the end decided to use the pin 6 for on/off, and this tiny change allowed me to use it simply... by pushing the pin 6 ( 95)up , we disconnected the permanently on, and had a pin for the leads to the switch.... simple...

But if your o/head room is a problem then you can wire as it is and use temp pins for on/off, or isolate pin6 and solder direct to mini board to switch....

Hi Oz,

Thanks for clarifying that, here is how I have implemented the modification. The 3 pin connector fits in nicely against the trim pot, just have to drill a hole in the right spot and cut the track around it and the track to pin 6.

Yes Oztules, very nicely explained from our original discussions.

I will take up your PINK colour as a track/cable modification indicator, I like it, as it stands out.
