I've recently put together one of Dezbaz's reproduction 6100 HV boards. Every component is brand new except the T900 transformer.
It works great for a minute. B+, measured at pin 5 of the P900 connector, starts at 180V when powered on. There's a nice picture on the screen. Pin 1 and 8 measure around 25.2V and -25.2V.
However, after a few minutes R901 starts to get very hot. B+ starts to drop drastically. At one point R901 got so hot it de-soldered itself before I could turn the monitor off.
I must have made a mistake somewhere, but I can't find it. Any help is appreciated.
