Reverse engineering the MLA-30 or any other product could be considered as a theft of Intellectual Property and publishing the circuit diagram without the owners consent a breach of copyright law.

The situation as I see it; one can spend well over a 1000 hours developing a product, then someone comes along and steals the value your hard work.

? To quote from your mail “ Anyway the repercussions could be interesting for various company's like Wellbrook,? who do indeed pot all there products, which would class them as non repairable from manufacture.”

What you are saying is incorrect; Wellbrook loops are repairable by replacing the head amplifier module.

Most other loop manufacturers offer replacement parts for their products even if the replacement products are potted. Put it another way, it is up to the product designer to decide the repair policy.
I was fascinated to follow this thread on reverse engineering the MLA-30, However by coincidence whilst I was reading it a news item appeared on TV, it seems in future, due to new EU rules, all items sold commercially must be REPAIRABLE. Something to do
with cutting down on disposable throw away items !

I've always seen potting as a dual function....one being to help protect one's intellectual property and of course keeping out the dammed water....

To date I have never managed to keep out the moisture, or stopped water ingress into any of my preamps.
