These are electronic circuit in massive epoxi blocks (one of them is cmoy headphone amp, manhatten style), looks nice but it is total senseless
how do you modify or repair the components ? yes it is not possble, if one part is broken you can throw away whole project

Well done to comment I have little experience In electronics I think we can make it coil against water

I think internal stresses from the "harder" epoxies during curing might cause trouble with PCB's.
Acrylic casting masses can have huge stresses. You can cast in many layers if need be.

As a student I worked at a company making DC/DC converters. They were then filled with brownish stuff that hardened.
Everything like temperature/humidity etc had to be just right or else that batch was crap. It was very toxic too.

Today's materials are much better, but be cautious and experiment before you put your favorite pcb under goo.

Nice, thank you.
Do you know about prices and where to get.
I am thinking about testin to suspend a shielding material for cauting my coil

LOL, That one crappy solder joint . You would be looking at it for ever and ever thinking, Eaaa WTH ?
