I'm not sure if that layout out is ideal. this maybe better.

I hope Project16 is well and comes back soon.
Music….yippee!!! The Wolverine is singing! All’s working, measured fine and letting it settle playing music for a couple of hours now. Will close the case tomorrow and enjoy the sound into the new year.
Definitely decided that I don’t have an aptitude for neat wiring or induction coil winding but be it as it may, I thoroughly enjoyed the building and looking forward to get my EF3-3‘s (that I built in tandem) into a case early in the new year.
Many thanks to the Wolverine team for the hard work and dedication and sharing it with us!!!
Happy New Year to all!!!

I received some helpful answers from @danieljw , @Bonsai and @EdGr regarding hum and hiss from my sources. So many good ideas what to check, I have compiled a to do list from your suggestions.
But don't get me wrong , the Wolverine anp itself is dead quiet. With Inputs shorted I can't hear that the amp is turned on with my ears 10 cm away from woofer or tweeter. To hear hiss from the tweeter I have to put my ears directly to the tweeter. To hear the remaining PSU hum I have to stick my ear right into the bass reflex channel and focus in order to think that I hear something. That's better then with any other amp I had.
Using a Salas Phono Preamp and my B1ish preamp, set to very loud a listening level, I stopped the music and listened for hiss and noise with my ears next to the tweeter. Nothing.
So my sources might be "noisy" but not noisy enough that it can be heard on sane listening levels. I will investigate further next year..
I would rather want to write a review about how great this Amp sounds! I am going through a lot of well-known LPs and every record sounds better then with my other amps. No sign of "Class AB Harshness" or "sterile Sound". Just a great amplifier that reveals the potential of the Salas JFET phono preamp.
Even my girlfriend stated it's the best sounding amplifier I have build, as soon as she heard it the first time. She said: "finally the bass is back". Note that she was negatively biased against the Wolverine because she could not understand why I need to build the fourth amp in two years.. Now she wants to listen to her music through the Wolverine.

The placement of the transistors is random.

So good to see people progressing with the builds. I'll catch up with you in January. Some hiccup with the shipping as the Heathrow processing center is worse than the Bermuda triangle at the moment.
Oh, no - @voxxonline I can't believe you still haven't received your boards yet? In that case it's a bit of a miracle it seems that mine managed to organise a break out when they did ...!
It is what it is. I am in no hurry to build though. I read up on bits of theory but it is still a long shot from a complete understanding of small signal amplification. So I take this delay as an opportunity to plan my build a bit better.
Sitting back and enjoying this phenomenal amp….tight bass and absolute clarity!!! it has loads of grunt and is just wonderful to listen too.
it’s quiet and I don’t have any turn-on thumb. Using the DiyAudio soft start and currently no speaker protection (probably my next project)

Well done Steve!
Just a suggestion - put a rubber grommet in the chassis baseplate hole for the mains wiring and also put some heatshrink or tubing over that cable for safety reasons.
Great build, and I would recommend speaker protection when you can.

The plans changed a little, the power supplies will be placed vertically and the soft start due to the large diameter transformer i have at my disposal only 15 centimeters high. I have seen it at 800 VA trafos have a larger diameter. Also the two capacitors at the output of the board significantly limit the space as well as the heatsinks of the drivers. So the transformer will be placed below and horizontally.
Ηappy new year to all of you.

Hi Guy's,
🥳 Happy new year to you all. 🥳
I've really enjoyed being part the DiyAudio community this year and especially participating in this thread. It's been awesome to see so many people enjoying there time building the Wolverine.
I hope that you all have enjoyed your new years celebrations with your friends and family.

Happy new year diy'ers. Remember, it is the journey not destination
Happy new year everyone!

Hi Guys,
Wow, there are some amazing and inspiring Wolverine builds underway. I can't wait to fire up this beautiful amp and start listen to music. I have made a lot more progress on my build through December and thought I should post some photos. I only need to complete the three heatsinks on the PCBs and mount the output devices to the heatsink and I can start testing them on the bench.
I haven't decided on an enclosure as yet. I would like to thank all who have contributed to this fantastic project - much appreciated. Happy New Year to everyone!!
Cheers
Paul

I would recommend the DIYA Store 5U or 4U cases with integrated heatsinks. 5U especially if you plan on dual transformers/power supplies. And your build looks great so far, congrats. Season's greetings backatcha.
I am pleased to say my W boards arrived today, as well as 85% of Mouser's components and the bench power supply. Some minor items to be ordered, but all in all, my 7 week's wait is over 🙂 The longest delivery wait I have ever had.
