"I checked with ACA just before posting, and they said they will have 100 kits available on Sept 7, and another 100 on Sept 20. They sell out quickly, just letting you know."
We’re working on producing a big batch. We do have some in stock but yes, I’m sure they’ll go fast! Perhaps Jason can organize a pre-order approach for the ones that are coming.
Unfortunately Steve Guttenberg seems to only have tested 2 ways of using the amps, the stock 2 channel stereo and I think the balanced monoblocks. That would mean he hasn’t tested the Bridged monoblocks, which I think should be even more “warm and cozy” than the 2 channel stereo, and the Parallel monoblocks, which be very similar in sound to the 2 channel stereo configuration but with more power into speakers with lower impedance. Thing is, many speakers that claim they are standard impedance have big dips which are low, so this configuration can be awesome with some speakers.
Hey!, maybe he’s planning another episode to test these configs. We sure did our very best to make it clear what’s what with the new rear panel!

We may make an upgrade kit with the Panel, on-off-on switch, wire to make the small changes to the rear panel wiring, plus the chassis threaded inserts. That would make any 2 channel chassis absolutely up to date. But I think the panel alone is going to be available alone as it’s the main thing, and the DPDT on-off-on switch and the bit of wire is available at most suppliers. Parts Express has these. We can make a BOM.

Gianluca is only discussing the chassis' as he IS the HiFi2000 chassis maker. We send the Parts Kits from the USA and they always drop ship the chassis' from Italy, which usually arrive shockingly fast and reliably. Until we run out, parts kits will be sent out immediately from the US on receipt of the order. This will give you time to get the PCB populated until the chassis arrives!

48vdc ACA, aka Kampana in Manila is alive...
4 x 48 vdc @4 amps power bricks, and 2 boards of dual channel ACA boards, using the Conrad Engineering 350 x 151 x 60 mm heatsinks, temperature was 61 C* at an ambient of 30*C.......IRFP150 mosfets.....bias at around 1.4A.....the whole rig dissipated 260 watts.....
