MOTS are typically 2KVA, so 8 -10 amps typically with switch-on surge. You can do the same as that YouTube video, but its very crude - sledgehammer approach with absolutely no safety against overloading - far better for what you are trying to achieve (which is quite delicate) to have control, repeatability and be a bit more subtle by using euro 15 of electronics and doing a proper job. Filtering is easy - just use a filtered IEC 320 EN 60320 C14 (aka "kettle lead") input mains socket - C12/C13/C14s are good for 10A @250VAC. Do it once. Do it right! (and be safe!)
