In-circuit LOPT/FBT Tester kung sino interested magpagawa nito. I made this tester since 2009 functional, kung sino lang ang interested kasi mas madali lang pag trouble sa TV, Here’s the design for a low cost, easy to build and use battery operated ‘shorted turns’ tester for
line-output or ‘flyback’ transformers, and other HF wound components like deflection yoke windings
and SMPS transformers. Tests have shown it capable of finding at least 80% of LOPT/FBT
faults, so it can save a lot of time and trouble. Small and rugged, it’s well worth a place in the toolkit
of anyone involved in servicing TV receivers, video monitors and computer power supplies. yun ang magawa sa LOPT/FBT tester. Tatanggap ako nang order.
