I spent lately many days examining several amplifier designs and simulating the ones with LTspice schematics available. As the result of this effort I become impressed by the quality of the Wolverine design. This makes me ask if there are Wolverine PCBs from the 4th group buy still available, and if not, are there any plans for a next group buy?
Hi Guys,
We're excited to share some great news, which we hope will enhance your amplifier building experience.
The Wolverine team is thrilled to announce that anodized heat sinks are now available for our project.
These heat sinks are specifically designed to fit perfectly with our current boards. Here's what we've got:
@jjs is in the USA, and I am in Australia, so please PM whoever is closer to you, and we'll arrange some for you.
Happy building!
Best regards,
Stuart & the Wolverine Team

- Heat sinks suitable for the IPS Boards V4.9.
- Pre-driver heat sinks designed for V4.2 of the EF3-3 & EF3-4 Output Stage Boards (OPS Boards).
- Driver heat sinks for V4.2 of the EF3-3 Output Stage Boards.
- EF3-3 IPS, Pre-Driver & Driver: $27.5 USD (6 Heatsink Total)
- EF3-4 IPS & Pre-Driver: $22.5 USD (4 Heatsink Total)

After contacting fireanimal he informed promptly that Wolverine PCBs were still available, and that stuartmp took care of the deliveries to Europe. I contacted stuartmp and sent my order mid October. The mailing and administrative costs for a delivery of 2 x 2 sets (total 4 PCBs) of Wolverine PCBs and heatsinks to Finland was about 37 USD. The PCBs arrived mid November. Customs declaration did not cause additional costs.
At the end of October I received a Dropbox link from stuartmp for downloading the documentation. It is a huge package of information containing everything you can imagine to need for an amplifier build, especially a very detailed Build Guide covering everything from component selection to testing of the finalized amplifier. The information package did not cover the Wolverine PCB part only, but the whole amplifier plus valuable general information.
After receiving the PCBs, I was amazed about their quality. They are real artwork, pieces of fine technical art. Additionally I have never seen so much useful information printed on any PCB. Especially the component references on the bottom side of the PCBs was something new to me - a really practical thing regarding testing and possible fault location. I am completely satisfied also with the PCBs.
If a serious enthusiast is not able to build a quality amplifier based on these PCBs and the accompanying technical information, he must blame himself only. Implementing this kind of construction project will raise at least my amplifier know-how to a new level, despite earlier design and construction of several amplifiers.
I really appreciate the work of the Wolverine Team and thank the team for making the results available at a reasonable cost.
Kind regards

Announcing the Wolverine 5th Group Buy - Pre Order Open Now!
Register for the Wolverine 5th group buy
Hard to understand, but I think he's looking for a drill pattern for an EF3-3 with MT200's to prep an existing heatsink ? (AFAIK we only have EF3-4 MT200 drill patterns in the build folder and all modushop MT200 also EF3-4 400mm deep)
The updated hole patterns are in the Dropbox folder. A link to that folder will be sent to you once your boards are shipped.
Ok guys a bit of news today.....
After alot work from the Wolverine team
I have in my hands the V5 EF3-5 pair
Mirrored boards and parts in my hands.
Special thanks to Stuart for his extra efforts to make the mirrored boards a reality.
Time to start building!

I posted in the build thread, but here is a pic of the IPS mirrored 🙂
I would highly recommend the pre-made heatsinks

We would like to announce another option for the Wolverine Version 5.
If you are planning on getting in on the PCB group buy, the V5 EF3-5 option which has 5 pairs of ouput devices is capable of running higher supply rail voltage for some more serious output power options 🥳
Due to the voltages involved this is for experienced builders only....
Please see table attached with the various rail voltage options and a scope capture with a 4 Ohm load.
