With completely DIY chassis, except for the Schroff 19” inch front panel and the Fischer Elektronik SK 139-200 SA all is cut, drilled and tapped by me. Even with good tools available like the pillar drill, precision could be better, and at least I do small blunders I have to conceal.
So all this labor will next time be better used elsewhere and money spent better on a a hifi2000 chassis.
The 500VA transformer was intended for the ZV9, but after chatting with Super_BQ I think I shall change to two 300VA transformers.
BTW the rear handles are IKEA.
Next step is backplate holes. And maybe something on the front panel. And the top cover must be cut and drilled.
To be cont’ed.

Wonderful work!So I have to finish to keep up…. But I am so slow. View attachment 1095803
Let’s hook up some time, I am in the general Oslo area.
Quasi newbie here. I just finished carefully soldering my first ACA mini kit together (one item wish list this year, https://firstwatt.com/pdf/art_aca_mini.pdf with "updated BOM list 10/22 per NP"). I dipped in my toe because I didn't have to make the PCB and order all the parts, what a deal! I could have, but from work I know the time it takes to model it, create PCB and order, pick parts, and revise a few more times. The clarity is wonderful at modest volume into B&W bookshelf speakers off Craigslist when tipped up and placed a couple feet from room corners. Been lurking and reading articles at Firstwatt.com for a long time now (THANKS to NP for passing on your craft!!!) and grew curious about the variations in 2nd harmonic. Surprisingly, I found that I definitely preferred the Jumper installed for less 2nd for better clarity while swapping back and forth. I may still have to try out the PCB input kit that lets one vary this smoothly. There are just so many new details to hear in my CDs. Very pleased.

F5..... stil have some buzzing issues i will sort out soon i hope with help of you and friends around...
This one has 500VA transformer with 8x22000uF in power supply .... 50A bridges and pcb from diyaudio store.... also slow start and protection from Velleman
