I need some help on this one. I have a Panasonic AG series vcr with a bad power supply. I replaced the bad bridge, caps and the first stk reg. But I can't find the STK5339B anywhere. TriTronics says it's NLA as does MCM and Panasonic. Does anyone have one colecting dust in a bin somewhere or have a place that carries them?
