Hi All -
The store was out of stock for the F6 kits for a while, and we wanted to make sure that everyone that requested notification when they were back in stock had a chance to get one before they vanished. The sale site is "hidden" from anyone that does not have the link.
We have a few remaining. The link to purchase is below. We'll leave it hidden for a few days so people that frequent the site but may not have requested notification can get them before it's open for the whole internet to see. We always want members to have first access.
F6 Complete Board Kit
The only configuration offered is as a full board kit. @Nelson Pass was incredible (as always) in helping us get the parts.

The kits will have all the parts to stuff the PCBs and include:

So glad you posted this as I couldn’t find it. My kit is due on Monday but the link in the delivery email takes you to a 404 page. Had a panic I’d bought a kit without Mosfets… Due Monday. Now to think power supplies (obviously I should have added those to my shopping list, but was worried I’d miss out).

^ Thank you for commenting. It's kind of you to say. We worked very hard to keep the total cost lower than the combined cost of the previously available partial kits. One reason (among many) for the delay in getting kits back in stock was parts availability and cost in a post-pandemic world.
That's a good deal and I believe less than what I spent on mine 8 years or so ago. This is pretty remarkable especially considering the Jensen transformer is somewhat more expensive now than pre-pandemic.
Have fun guys.

I've pulled this project out of storage and started gathering parts for whatever's missing. I'm using a dual mono power supply and have a pair of 300VA transformers and a pair of 600VA's. I'm thinking the 600VAs would be complete overkill for this and not really gain me anything?
Also, where are you guys getting your large aluminum heat sinks? I'm making a custom chassis for this project.

A single 300VA will run it beautifully.
For heatsinks I'd give @Gianluca a call. https://modushop.biz/site/

damn, always counting on weight, as it is flying

dual 300VA will run it even more beautifully
I'll save the big toroids for another project then, the dual 300's are also a lot more friendly on space.
The stuff from Modushop is very nice but being in euros the parts and shipping will cost more than my entire build. I'm planning on building a kinda lookalike Krell KSA to match my existing Krell preamp.
Upon digging deeper, looks like Mouser carries a huge variety so I'll most likely go that route.

But two will run it better IMHO. 🙂A single 300VA will run it beautifully.

@SRMcGee thanks, I had a look at those and they have some decent but pretty expensive offerings. I actually found some pretty good looking hardware on eBay so I've reached out to the seller to see what they can do for shipping.
I really wanted some of the big chimney style heat sinks that are used on the older Krell amps but the price on those make them basically unobtainable.

Arrived today, all is good. Thanks^ Apologies that the e-mail did not work properly for you. I'm very happy we have a few left. PM me if you have any issues with your purchase or notify the helpdesk, I see those flags too.
This is great. I’ve wanted to build an F6 for a long time. Just got mine up and running and it’s a great amp.
Ok, I always discover my 4 Semi South transistors in my stash and get excited and come to this thread but at least now I remember that you guys tell me that they are the Wrong Ones for the F-6!
So is there anything they ARE good for?
They are labeled:
