Hi Matt, can you please tell which boards are you referring to? I don't see any place for jumpers on the regulator boards and the capacitors on these boards are labelled 'C1 to C4'. I don't see any 'C22', not even on the 22000uF filter boards. Thank you.

If you use the panasonic capacitors, you'll have to cut the supporting stand by 5mm. Alternatively, use Nichicon UVZ1V102MHD as suggested in post #664.

And, you'll have to use a 8mm standoff. I cut my supporting stand (bottom part) by about 6mm. Don't worry about the treads, it runs deep, probably 10 to 12mm deep.
The only thing I am not sure about is whether we should apply thermal grease between the 'U' regulator holder and it's heatsink.

The polarity of the LED on the protection board. Please note that other diodes (D7_L, etc)polarity as well.

You can do it without the protection board but obviously, you won't have speaker protection and the standby mode.
Use the CRC filter board. Then you need not the auxiliary transformer and also the mute relay on the daughter board of the main board.
You can opt for the slow start board and the speaker protection from diystore but i am not sure if you can use the speaker protection board.
thank you pmchoong
I am asking as It Is not so simple to do all protection board setups - many smd componens, additional components set up and etc.
I will use protection from main F5X amp pcb
I guess that I can use also Ve regulator If bypassing relay
I do have protection pcb V3 which has reported to have Issues and will try to set It up later

If you are using r3 of the protection board then you need to do the wire connection on the board. Also, change the value of R32 to 2k ohm and R33/R34 to 120 ohm.

About the protection board. Do I need to set up all the jumpers before I can test the board?
