Did you ask Hypex about warranty or is this just your opinion? I asked about mods and they clearly stated they would void warranty.Good luck with trying that one on. Warranties cannot be voided for something as simple as a blob of RTV on a bright LED to dim it. I'm not talking about slathering silicone all over the PCB and making a mess. Anyway, have a good look at Hypex boards if you want to see excess silicone/rtv...
Hypex use of RTV to reduce shock and vibration issues is by design. So would be part of the testing they do. While acknowledging your suggestion to test first, not everyone has a good thermal camera. A pair of scissors is much more accessible.
But in any case, any warranty with Hypex is completely irrelevant to the purchaser of an assembled amplifier. Their contract and associated warranty is with the assembler/reseller. Too much attempted buck passing in this world if you ask me.
I have had these discussions with Hypex and it would be relevant. It could also be relevant to the manufacturer as the modules are warrantied by Hypex to them. I considered becoming an authorized Hypex repairer and my understanding is Hypex would honor their warranty regardless. No buck passing as you allude.
Bottom line, the LEDs on the modules shouldn't be lighting up the interior and highlighting the poor fit of the top panel to the base - it looks terrible. But then again, some gamer dudes might think it's some how cool.
One camera angle on one case design is hardly a major problem. I have other cases and the LED brightness is not a major concern. Am sure Buckeye or his customers are smart enough to employ simple mitigations if needed.
