Inrush limiter question


2012-02-17 5:04 am
I always use them in series with the Transformer primaries on my power amplifiers, but switch them out after the large inrush current has settled. Basically a Triac in series with 4 CL40 in series parallel being switched out by 4 parallel relay switches, have used hundreds of this combo over the years with no failures, bullet proof

Best of luck

Here is what I did back in 2005, just an exercise.
B+ starts slow, and waits for filaments to warm up. As soon as tubes start drawing current B+ comes up faster.
