No need so much elaboration, if you need re-polarize the amp (For example for pass from 1.6A to 2A), this would be nice for do it again without disassembly

I can loose a battle but I win the war
The protection PCB is completed and fully functional and tested.
I complete the building of the F5X and now is playing music since one hour
I bias at 1,5A with 0 mV offset and I have to say that is really hot!
I will recheck both bias and offset in two hours and I hope that the bias is not going too high.
I have to say that is not playing at his best, is connected to a DCB1. I am waiting a Rane BB22 (passive converter RCA/XLR) that is on the way.
I will use it until the F5X Preampli will be published (I think that I am not the only one )
Thanks to everyone of you for your kind help.
A particular thanks to Patrick which enabled us to build this TOP Class amplifier and to Mark Lai for all the logistic support.
Attached some pictures (apologize for the poor quality)
All the Best,
Enrico

pics 9 & 10.
What type of glue have you used to glue everything to the ceiling?

Or
Can anyone tell me how to invert the pics using a facility in Win7/Firefox?
