I have it all in my cart on my home PC, at work right now, will post later for you.
The total for the BOM that Prasi posted was $226.51 Canadian, which converts to about $175.00 USD for two channels.
That did not include the TIP142/147 output transistors, and for the out of stock 10ohm 2 watt resistor, I subbed a larger 3 watt one that could be put in vertically.
Here is the mouser cart,

Please ignore the above cart, I posted it in a rush and it had extra Faston connectors on the list and no board part numbers.
Here is an updated version,

R37 is on the list twice, it is supposed to be the 2 watt version at the bottom of the list, but it is back ordered for 6 months so I substituted a bigger 3 watt version that can be put in vertically.
The BD139 is currently on b/o at Mouser right now, but Newark has them in stock, but I left it in the cart.
Total for the cart with doubles of R37 and the b/o BD139 is $184.00 CDN or ~$140.00 USD for the two channels in the cart.
Sorry for the double post on this to get it right.

Man, I might have to build one of these when the TIPs are available again. Are Prasi PCBs still available anywhere?
Guys I have Prasi PCBs . Also I need to thin a few projects out. AB100 may unfortunately be one of them. I have a stereo pair pretty much populated, including output devices. Let me dig it out .
I think FH9 and AN39 have my attention more.

Here's what I can offer. I think everything is there apart from the output inductor.
Populated with Silmics, Vishay, KOA BPR.
£100 plus shipping.
I'll look for the boards. Think I have a pair of these green 2cap left.

What did everyone use for an input capacitor on their AB100?
Here are three choices I am looking at,
ELNA Aluminum Electrolytic Capacitors - Radial Leaded 100uF 63V 20% Audio SILMIC II
Vishay Film Capacitors Polyester, Metallized 2.2uF 10% 100volts
Panasonic Film Capacitors 450VDC 2.2uF 10% MPP L/S=15mm
Last one might not fit within the 18mm long 9mm wide space for the input capacitor.
Other suggestions?
Thank you,
david.

I totally hijacked this design and turned it into a "mirror magic" design with 3 X 3 lateral fet outputs. Beginning layout passes were posted earlier in this thread (mid-2017). Boards are on order, and I potentially have enough output juice to run me out of the house... I'll start a new thread once I have the beast up and running.
Yes, indeed - I'll be needing to put in a largish order at Profusion...
I finally got my Exicon lateral fets, no thanks to the clowns at DHL. I had to go to their service location to pick them up, and believe me, they didn't make it easy. There is no sign to mark their depot, and when I finally found the place, I had to flag down a security guard to tell me where the customer service office was.
On another note, I remember asking the folks at Profusion what the std tube qty was - they replied, "no sir, we ship them in trays". After that declaration, they shipped my parts to me in tubes anyway....
After going to all that trouble to pick up my parts and PCBs from DHL directly last night, finally the clowns at DHL decide to show up at my work place today when we're actually open. It's enough to make a person tear their hair out by the fistful, which is something I can't afford to do,

Please let us know what changes you are making (if any other than mosfets) to make this work . What was the minumum amount of Lateral Mosfets you had to order ?
Looking forward to seeing more 😀👍
Very early in the game (2017), when I was doing a modified layout, I got a comment from some punter that if I "touched" it, it wasn't an NP design anymore. This got me a little frosted, so in reaction, I sorta - just touched it all over, so the new design is 100% me, and 0% NP. The closest design is one I call "Mirror Magic", that used current mirrors combined with a follower stage to drive two sets of lateral mosfets. That design worked pretty well, and got a showing at Burning Amp 2019. The new design after the carnage supports 3 sets of complementary lateral fets, so it should have a capability in excess of 100 W/channel with properly implemented boost supplies on the driver stage.
BTW, I ordered 30 pieces each of the Exicon 10N20 and 10P20. I finally was able to pick them up directly from a DSL hub last Thursday night, after DSL failed to deliver to my workplace about 4 times in a row, due to their total inability to show up when we were actually open. No DHL, ever again...
What I did for this design is documented here, more or less:

The original "Le Mutant" amp still does yeoman service in my living room, driving a pretty efficient pair of Klipsch speakers.

Thank you kindly @wrenchone ! I have started reading the thread (interesting that it spans over so many years) .
For any other interested parties , here is where the "Mirror Magic" starts : https://www.diyaudio.com/community/threads/le-mutant-class-a.191986/post-4855868
