I haven't seen any V3 builds yet, so here's mine. It's a stock build using the Modushop case, nothing fancy other than the two power supplies. I'm running it balanced using Leo's active RCA-XLR converter. Haven't had a chance to listen yet other than to confirm that it's working.

If anyone wants to build this version I'd suggest getting Allen-head M3 screws - the Philips-head screws are very hard to remove if you need to take anything apart, and the front panel screws on the right are practically impossible to get to with the second PSU in place, but it's not bad with an Allen wrench. Also it should be noted that the speaker terminals are not spaced to accommodate dual banana plugs, which is my only complaint so far.

Very nice work and use of the RCA to XLR board. Here's what I did with 5 Ultra's and 3 Rectifier boards that that Leo built for me as a Thank You for helping him out at the 2020 AZAClub's Speakerfest 2022. The Chassis was design by a friend of ours in Chicago with my Spec's. I'm also using an Orchard RCA to XLR adapter for my single ended phono stage. It feeds into a BAT VK50-SE.

One Rectifier Board for the Left Channel, one for the Right Channel, and the 3rd feeds the Center & Surround Left & Right Channels. I add a pair of 15,0000uF Caps for extra reserve for those three channels. Power by a 1500VA Antek Transformer.

New to this forum and I just wanted to post my assembly approach. I made a number of internal wiring changes and used Wago connectors rated at 60amps and 670v max. I am still reviewing this amp and it seems to be very neutral, good detail, with tons of power.

Taking a quick look at your picture, you will want to twist all the AC lines together like you did the DC.
