thanks guys for the advices. the copper shields are soldered but didn't notice both ends. at least i know now the direction of these ICs. for the mesh, i'll buy it this weekend and will tidy it up. (sorry mga sirs, walang ace hardware dito. will have to go to sim lim tower)
just OT, dami pang ICs nung uncle na binilhan ko. ang binili ko talaga yun Acrotec 6N-A2050.
