The potting is very hard to remove and when someone want to re-use the loop, the easiest way to do so is to saw the amplifier housing off. and use a IP66 rated box. I found a small binocular core like a AMIDON BN-43-2402 and a biliar found toroid like a FT-23-43. At about 30% of the depth of the housing appears to be a circular PCB, which is very difficult to remove without destroying the casing. To be continued, 73, Roelof, pa0rdt
