Well done I think the only safe thing to do with those amps would by to send them to the doc for fettling and checking.
1. No ad-hominem
2. No spamming or shilling
"I am 100% happy these fuses are legal I have seen the certification myself which is not for disclosure to other parties".
"If you have doubts about the legality of the product feel free to take it up with the manufacturer".
So I did & somewhat unsurprisingly no response is forthcoming, but I'm like a dog with a bone on safety issues and shall continue to pursue this lack of clarification.
I find it odd that safety certification is not for publication to the wider public? If they are certified then why the cloak and dagger approach?
How terribly inconvenient
