That is the way that I have done it in the past. I had not heard of this process of bringing up the voltage slowly with the horiz output tubes disconnected, until I read some posts in this forum. Can somebody explain the theory behind this? My *guess* is that the flyback could possibly be cooked if the horiz osc does not start before current flows through the horiz output tubes. Is this the concern?
