Either is fine. Trust me...I build a lot of these.
165v is Minimum, so as long as you use a reputable company like Tiger, it is fine.

If available, I'd like to order two boards; could you please advise process for this.
Many thanks.
Can someone answer a newbie question for me? As I’m a 100% newbie on this stuff
What’s the cost for the board and all the parts, not counting a case ?
And is this project ok for a newbie? I am a fairly accomplished solderer and have quite a bit of test gear for testing my work as I go. I have multiple meters oscilloscope and many other items such as that. I’ve never tried a (from scratch) PCB type project like this and would very much like to build it, and do I need one board or two boards for stereo?

If you follow the BOM, It should be the easiest thing you ever build bar a pot in a box.
PCB is £20 plus postage and the matched MultiFET boards are £45 a pair.
Parts cost for the PCB is about £100ish plus some output caps of your choice.
If you require any further information, just let me know.
Thanks,
Oliver.
I'm interested in this. Is shipping 15 to the US and 20 per PCB, so if I get two it would be 55? Pardon the lack of the GBP sign.
I am curious about another thing after reading thru the thread quickly, I see something about Tiger transformer. Is that a manufacturer in EU for the EU only or any market? I see some sourcing it on eBay, but I am hesitant to order from China for several reasons where some are morally derived, and if possible to get it from EU I'd rather go that route.
Thanks,
Bjorn

Hi Bjorn Tiger Toroids are in the UK. I used them for my BB3 transformer; nice guy to deal with. Send him a message.
Tiger Toroids is a British company offering a fast and flexible solution for transformers and sinewave inverters.

Postage to the USA is £20, as they are now charging a fortune for tracking the parcel.
£20 per BB3 PCB
£45 per pair of Populated MultiFET boards.

Hi all,
As some of the eagle eyed amongst you may have seen, there has been an adjustment to the BOM.
The BF861B is now "end of life" and is no longer being manufactured.
Obviously this is very disappointing news but it's not all bad. We have identified an alternative Jfet - The 2SK932-22
I have made up a couple of MultiFET PCBs and installed them into my BB3. I am happy to go forward with these Jfets as there is nothing of note (sonically) that i am unhappy with.
These are very capable replacements and the best part is the Fets are a little bit cheaper too!
I'll add a part number later today or tomorrow.

Hi Oliver,
I finally received the PCB (3rd one) and multi-FET boards this afternoon. Many thanks for all your efforts. The first board you sent me (March) has definitely disappeared into a black hole somewhere. With everything being messed up the way it is, my daughter's wedding was postponed to next year April. Bas kindly sent the 2nd PCB to my daughter (thanks Bas), who has just forwarded it via DHL (last week Thursday) with a few other items (LP et al).
Now to get building - first the PCB then the case.
