Hi all,
Long-time lurker, but first post!
I'm considering a build of the F6 amp and getting most of the parts and kits, including the psu kit and chassis from the store.
I'm just looking for some advice or recommendations for the PSU parts that lack part numbers on the BOM.
After researching, it seems like this is a good choice for toroid, the Antek AS-4218: AS-4218 - 400VA 18V Transformer - AnTek Products Corp
And I saw these caps recommended as well: Blocked
What would you recommend specifically for RS1, RS2, CX1, CX2, CS1, and CS2 on the BOM? Is there any other parts I should change that are already listed on the BOM with the above toroid and caps? Is there any misc items you'd recommend picking up before I embark on this new journey (I have all the soldering equipment needed, tons of wire, etc, already)?
Thanks in advance!

Transformer is great.
Caps are waaaaaaaay too big. Use these -

Thanks 6L6! I’ll grab those caps instead.
I found the snubber values for the AS-4218.
Cx 10nF
Cs 150nF
Rs 18.3Ω
I’m still having some trouble narrowing down which parts to pick up to fill these slots. It seems many First Watt amps have been built with this psu and the AS-4218 toroid, so surely there must be some go to parts that I’m just failing to find.
Unfortunately my skill level at present is basically put the part on the board and solder it in, but I’m trying to improve.
Thanks again.
