Default Maximum operating hours

I notice that the ACA gets hot easily. Is there a recommended maximum operating hours for this good sounding amplifier to avoid overheating?

Just measure the heatsink temp. Around 50c is okay forever. This was just discussed a page or two back. So there is a bit more info if you search.

Default ACA's and heat

Have run mine 24/7 for periods of weeks. They get to a certain temperature and stay there unless the room ambient temperature changes. Just make sure air can move under them and around them.

I know what gauges I need. Can anybody identify what type or brand the wires for the kit are? Or simply identify some quality wire for power, signal, and output?

I have one of the original kits, I have not shut it off in about 4 years now. Well occasionally it gets shut off to move or clean, but mostly left on.

Billy, thanks! It only goes to show how durable the parts are.

I am done building my two monoblocks. My Q Acoustics Concept 20s are perfect for the ACA. I have not yet tried them though with the Magnepans.

Bear in mind that I've barely made apprentice amp builder status and that I'm not blessed with golden ears - in my case, I opted for generic offerings. The important factors that I looked out for (after gauge) was (in no particular order):
  • Solid versus multi-strand
  • Tinning of the copper wire strands
  • Temperature rating of the insulation (if you're concerned you can take this to the next level and check the build/design standard)
So, on that basis I landed on multi-strand (less prone to damage due to manipulation), tinning (minimise copper corrosion), temperature rating ca. >=85C (given how warm Class A amps get, it seems sensible to select wire with insulation that can handle a bit of heat, so the higher temp rating the better {within limits, i.e. $$}). Even so, life's a compromise and there are varying shades of grey that will be influenced by personal taste/rationale.



Hook up wire can attract a swag of opinion, e.g.:
Best Hookup Wire? (for component internal wiring)
You could check that thread to gather intel. Probably best to avoid sending this thread on a tangent.


Good luck with your journey.
