What this bitter and frustrated grandpa in his signature says happened once and was 13 years ago, it was in 2011 and had a different reason than he claims.
The partially epoxy covering did not damage the circuit, but rather actually had a protective function for the components and is comparable to how H. A. Dumble completely covered his circuits with goop.
The reason for this at that time was so that his then best friend Mike Fortin, near whom this grandpa lives, would not again drill his curious eyes into my then very current circuit of my preamp and not copy another Larry circuit and then use it as his own development presented, just as Mike Fortin had done several times before.
But with such old, bitter and frustrated grandpas, such bitterness eems to be so deep and fixed in the brain that they can only be eleased from it by the impending grave?
