Great thread! I saw the title "broke my class D".... and I had to chime in, both for some self-therapy, (since I had two class D's crater. UGH) as well as a warning (and, Todd - we don't live too far away from each other, so I'm going to guess our utility power is of similar quality, OH, and I have a teenage son too)
So I bought new-to-me Jeff Rowland 501 mono blocks in November '16; plugged them directly into the wall (as recommended) and left them on 24/7 (as recommended). Loved them, listened to them, played them. I went up to my music room in early Jan '17 and they little blue lights were on, then off, then on, then off. Randomly. No sound. Cycled power. NOTHING. @#$@. Did this over the course of a few days.To make a long story, short (ugh, bad electrical pun there), after about an hour on the phone with Jeff Rowland himself, we determined that both ICEpower1000ASP modules were hosed. (Let me tell you, even the used price on these amps stretched me. I was NOT a happy camper).
Jeff treated me super, super well. He had two of the latest (Rev J) boards in stock which he sold me at the best price I'd seen anywhere (and they are warranted from JRDG), I installed them, and I'm back enjoying. Not before I put a large isolation transformer in the circuit, AND a voltage safety circuit (1/2 cycle response time, will 'open' a 15A relay) and surge suppression.
LESSON: even if we can leave Class D's on all the time, I turn mine off and disconnect during storms, and now run serious power protection.
TEENAGER: I'm watching mine like a hawk. Write your cell provider about "parental controls". I'm really mad they have no accommodation for parents. Cell phones are just about ubiquitous for 'child safety' and connectivity, especially now that they are driving. BUT....it's the wild west out there on them. I can control access home computers, but not those. Please write your carrier, and ask for the ability to specify DNS servers. That would allow us parents to use web-filtering services like OpenDNS.
