DIY Class A/B Amp The "Wolverine" build thread

The lids are in,
The aluminum still needs to be anodized
And the base legs

Awesome work!
Fantastic detailing with the jagged claw marks, Bravo.
:cheers:

Edit: The more I look at this amp, I don't know if I'd anodize the raw aluminum in black. I think you'd lose the Wolverine name and claw marks if all was black, maybe a clear anodize for protection? Just a thought.....

As part of this 5th Group Buy, the IPS, EF3-3, and EF3-4 boards will now include mirrored versions for Left and Right channels! These allow inputs at the rear of your chassis and outputs on the lower heatsink half, all while fitting the current UMS (with just 3 new holes for EF3-4, courtesy of Gianluca’s updated drill pattern). Huge thanks to Mainframe and DanielJW for prototyping, Harry for BOM review, and Jeremy for schematic checks. Update your order or join in to snag these game-changing boards!"

That's right, this is stainless steel, it will only be brushed for polishing, the aluminum ones are the sides and the cover of the transformer
 
The great modular concept of the Wolverine amplifier makes it possible to test differnt IPS designs. I just finished a prototype PCB with Bob Cordells IPS for the DH-220C Mosfet Power amplifier. It is quite interesting to compare BJT with FET input stages. So far the THD numbers are similar to the original IPS. S/N is really excellent.
The only thing to be careful is the bias spreader because the VAS bias current is different.

Nice Job Stani, I built Bob's DH500C a couple of years ago it is a great IPS.
