Report: -DBT constructed. -Inserted correct fuses in correct slots. -removed all connection from L and R amp sides. -Out of sheer paranoia and the dream I had, I pulled the main caps, checked everything (was fine), and reset. Neater this time, those huge lugs are an artform. Polarity was/is correct. Added 2.2uf bypass caps, cause I'm in the why not crowd. -Measured the bridge rectifiers (two round black things on right main board, correct?) with diode setting on DMM, and got what looked like good diode readings but this out of my knowledge range. I'm posting two vids. First vid is either 1st power up or 2nd. (tired lost count) Second vid is 2nd and 3rd power ups, or 3rd and 4th. On the second vid the relays kicked on which is interesting. I'm pretty sure the new OT are toast on the L channel again, probably lost with the 10A fuse. I've got more. I'll test thoroughly tomorrow. Should the DBT bulb be completely out?
