I got a full 10 hours in today and everything's looking great! Did a dry-run assembly and tested all earth grounds for continuity tho I had to remove a few spots of anodizing under the tapered bores that the belly pan attachment screws seat against as I'm relying on totally different belly-pan-to-case grounding than Devialet did. Went perfectly and quickly! Tomorrow's plan is to final-install the primary PCB and treat the 258 board pins with Caig Pro-Gold so I won't be expecting to be bowled over at first listen. In fact I expect things will be a little bright at power-up... perhaps even a bit 'shrill.' In my perfect world that'll blossom into warmth, articulation, depth, detail and its new persona over the first few weeks. Where it goes from there is out of my hands at this point but I'm hoping for the best. Actually I'll be happy with slightly cooler temps and normal, albeit perhaps a tad bright SQ that first week. Long as I don't have to go invasive on it again for awhile I'll be tickled to death! This project has gotten a bit long-in-the-tooth for me so I know the honeymoon has to be well over for you guys as well. It needs to end.
If everything checks out on initial power-up the plan is to leave it running, playing music 24/7 at -26-32dB for a full week. I'll have my first A, D and Supply temp comparisons 3 hours later if I don't have to power-down for some unknown reason. After that its on auto pilot for a week at the above settings without too much attention paid to SQ during that week. If it makes the first week's 24/7 run-time without incident I'll assume everything's working ok and its mechanically/electronically in order. Then I'll become a little more analytical/critical.
Could happen tomorrow but I'm not counting on it but unless something goes seriously south in a banana boat its hard for me to imagine to imagine going past end-of-day Monday before its warm, has a pulse and is eating again
