so in that case its an F5 not an F5 V3. I don't see the relevance of the board revision and it adds confusion.

It is the only version of that PCB that has the P3 trimmer.

V3 has wider traces to the outputs, different arrangement of components, and different component numbering. So important to differentiate.

Had a little free time today so I managed to get most of the Dale resistors mounted.
I would like to thank 6L6 for his pictorial guide, that was a big help, hats off to you sir.
Had to use my readers and a magnifying glass to read the values.
Verify, verify, verify, install.
So I can officially say I have started anyway.
I can not wait to hear this amp, already have a whole bunch of albums lined up.
Thanks to all of you guys who have given me guidance

Managed to get the two channel boards almost finished, save the thermal resistors ,the LED and its resistor.
So now onto the PSU, I have both Nichicon and Vishay 22000UF caps.
493-8646-ND Nichicon rated at 5000 hrs or 4645PHBK-ND Vishay rated at 2000 hrs.
Just wondering from anyone who has ventured down this path before me.

Thanks, Greg

Just to be clear, I meant the 2 single channel boards.
Ran out of solder doing the jumpers on the PSU and the only solder I can get locally is plumbing solder, so I had to order some online.
Anyway, the capacitor question is based on my total lack of knowledge and confusion as far as ripple current ratings on the data sheets.
My question is, if you had both in your hand, what would you do?

Either cap will do a fantastic job. You could flip a coin. Since both are rated 105 degC, Id personally go for the longer life rating.

I was going through things I need to order.
The chassis kit on the store page lists 20 standoffs in the kit, 16 for the two amplifier boards, 4 extra.
I would like to source at least 4 more for the PSU, just wondering if anyone knows the actual height of the standoffs so I can order a few more.

Thanks, Greg
