split sec lang ba ang pag bagsak ng B+
paki hang muna hot neto tapos check B+ kung babagsak parin.
pag bumabagsak parin, isolate mo muna tuner.
pag ndi, nag poprotect ang unit.

kailangan mag normal muna ang B+ mo kaya hang mo muna hot mo para safe.
baka may nakaligtaan kang capacitor na ndi mo napalitan sa PSU. check mo ulit. damay mo na rin resistor, diode sa paligid.

kung normal na B+ try mo ikabit ang hot at testingin mo kung babagsak parin.
nagpalit ka na ba ng mga ecap sa pri at sec? palitan mo na rin kahit good cyang tingnan.
huling option is ipa check mo fbt para mabawasan ang duda.
