Yes, that was stated in the BOM.
Thanks.

Nic, is your amp making music now?

NicMac · 8th February 2013, 06:32 PM

Yes, but one channel at the time and not with its own supply.....
I am fighting with the control board as I want this in before I close up the case.
To my surprise very little biasing was needed after shifting to the H configuration.

Hi Nic,

Are you done with the protection board yet?

Yes - but I cannot make them work as I want.
I'm in contact with ashaw and we are trying to solve the problems together.
I recommend keeping the assembly of these boards on hold for a bit. It is probably just my wrong, but anyway.
Note that the standard jumper configuration posted previously makes little sense for the F5X without regulated supplies.

The PCB has been tested before and proven to work.
So I am pretty sure it is a solveable problem, if any.

Just some patience while we sort it out.

I will probably wait until you sort out the control board issues with Ashaw before I start assembling mine. When you get the control board up and running as you want, do you mind posting photos before closing up your case? It would be helpful to see the board fully soldered and with the jumpers in place.

That means I will have to expose my SMD soldering skills in public

Yes, everyone should put their protection board building on hold till Nic has got it to work.
Then we decide how to "repair" for all of you.

Alexis is still taking charge, but I am keeping a watchful eye on it.

Are the 24pcs of 1k ohm Fukushima resistors for the CRC boards? We'll be using CRC until the regulator boards are confirmed to be working, correct?

I have done up my control board and waiting for ashaw to provide instruction on testing.
