I see that there is no soft start board included with the kit purchase. I will get one with the W12 PSU though, but it's probably not good for this specific build as it's supposed to be used with the class A amps.
Is the one from diyaudiostore suitable for this build? Or should I look somewhere else? Much appreciated!

Hi dovla83,
A soft start doesn't normally care what the circuit is. I haven't looked at that specific one, but a normal soft start will be good with tube amps, class "D", class "A" or "AB" amps. All it normally does is put a resistor in series to limit inrush current, then short it out once some time period has passed, typically 1/4 to 1/2 seconds.

Here is the PCB pic, maybe it can tell you more. Components are:
C1: 3300pF, X1 safety rated (Digikey: 399-9513-1-ND)
TH1: CL-60 (Digikey: KC006L-ND)
TH2: same as TH1

Hi Stuart could I ask if there's any Wima MKS2 / MKS4 caps on these new designs as Wima has just EOL'd them
😱😱 Not Wima. Bummer.
BOM has 1 or 2, but not strictly. . Alternatives are listed
More of the MKP/FKP range.

MKS2 only in the output stage. So cant say with 100% confidence at this stage, but very likely, yes.
Can someone confirm, is there a way to make sure you’re on the list? As mentioned I don’t have the ability to fill out the form, going old school. I’ve directly messaged Stuart from the email where I purchased the 4th version. It’s been a week or so and crickets. Just want to make sure I don’t miss out.
Thank you,
Dan
Thank you,

63VDC 1uF - 5mm LS - for both locations
MKS2-1/63/10A is listed as one of the many options
Dan, if you've sent Stuart an email, you'll be alright mate, hes very busy ☕. When the team are ready, there will be a participant wide response.

Now that I have PSU sorted out, can you please advise for what I need for the dual mono build (one chassis build, not separate monoblocks):
EDIT: found some answers, hope it's not wrong
IPS, Pre-Driver & Driver Heatsinks with Mill-Max pins installed - one package of 6 for EF3-3 build
2SA1381E / 2SC3503E Transistors - 8 pairs
Dual Bridge Rectifier Board - I'm getting these with W12 PSU, please let me know if not good for this build!
Speaker Protection Board - need a pair for sure plus the small trans you showed me (trans I need to get on my own)...
T-Ground Board - two boards for dual mono
Ground Lift - two boards for dual mono
EF3-3 Boards - how many is needed for my config, 2 x V5 EF3-3 + 2 x IPS or 4 x V5 EF3-3 + 4 x IPS?
Anything else missing from the group buy pool of parts I need to add?
Much appreciated!

Where is the gear being shipped from? Asking because if it's from US than I need to use different receivers address. Thanks!
I'm not sure dovla83.
I don't see any problem with it coming from the US unless they decide to include tariffs on that stuff as well. Once we have our national election the issue may not exist. You might be worried about nothing, but it is worth watching.
@Mainframe ? @stuartmp ?

I'm sorry, I wasn't clear enough.
For me in Canada, if the product is being shipped from US, than I use a courier service that imports the merch for me and delivers it in a facility in Mississauga where I pick it up myself. That is the prefered option for me but only if shipped from US. In that case, I need to use a receivers address that is in Niagara Falls, NY, than the courier handles it from there.
If it's being shipped from any other country but US, than I use my Toronto home address as recipients address.
Hope this explains why I need the country from where it's being shipped from. Cheers!

Sorry guys, I don't know anything re manufacture/distribution (being at the bottom of the world I'm useless here anyway). Stuart can hopefully answer that. He's likely flat out cooking up the V5 finishing touches.
I think in the past group buys there have been AU, EU and US distributors?
