Thank you all for the reply.
Would you plase explain why there is need to add a load to the +130V rail?
I followed the schematics and it seems there is no regulation/feedback for it, so why a load is required?
Thanks

+130V is the main voltage switcher regulates, all other pre-LV regulator voltages (+7V, +54V, etc.) depend on +130V being correct. ?It is sensed at the top of R1292 and adjusting R1293 to set +130V is one of the calibration steps. No need to touch it if +130V is correct, adjustment pot is in an inconvenient place when the PSU is connected. +130V comes out at a test point on LV board.?
