Members petejt Posted August 19, 2009 Members Share Posted August 19, 2009 We all know about particular amps that had their circuit boards selfishly coated in epoxy resin so their "trade secret toanz" would be harder to reverse-engineer and replicate. Well, I remembered that when pulling apart the front-loading washing machine to convert into a home-made wind-powered turbine. The circuit board is covered in clear epoxy resin, I guess to help keep it waterproof. There's only so much I can take of picking off millimetre by millimetre with my fingers, so I am asking for advice of more efficient methods. Thanks.

Members knucklefux Posted August 19, 2009 Members Share Posted August 19, 2009 that {censored} renders the circuit board useless. Link to comment Share on other sites More sharing options...
Members teemuk Posted August 19, 2009 Members Share Posted August 19, 2009 Heating softens the epoxy but isn't usually a viable solution with circuit boards. Methylene Chloride will also soften the epoxy - unfortunately, it will also destroy most electronic components. So... dental drill / mini dremel, surgeon's knife and lot of patience...?

Members knucklefux Posted August 19, 2009 Members Share Posted August 19, 2009 a very well known amp modder/builder had a tremendous snafu over that {censored}. it lead to one very pissed off customer and the modder/builder stopping with the epoxy.

Members knucklefux Posted August 19, 2009 Members Share Posted August 19, 2009 yeah... a guy bought an amp, sent it to the modder. modder did his thing, covered the board in epoxy, send it back. then something under the epoxy failed. modder refused to replace the entire board for free, even though it would have been serviceable were it not for the epoxy. owner bought a replacement board from ceriatone or mojo and had to pay a tech to install it. including the original amp purchase, the dude was about $3K into a stock JCM800.

Members knucklefux Posted August 19, 2009 Members Share Posted August 19, 2009 There was one that came to me, and I posted the pics here.It's old news, and the modder doesn't epoxy anymore.The amp in question was a JCM800, and the whole PCBhad to be replaced because of one bad part.The customer had paid this guy 1200.00 for the mods,and spent another 350.00 here making it run again.Thats the story. and this is the one i was referring to.

Members knucklefux Posted August 19, 2009 Members Share Posted August 19, 2009 maybe the epoxy was there to hide the {censored}ty work instead of the component values Link to comment Share on other sites More sharing options...
