For example, with tube gear, it's recommended that you use a variac or light bulb to limit inrush voltage. Can I just plug this in and cross my fingers? ?

Using voltage-limiting tricks is generally not recommended for digital equipment or anything with a switching power supply. If you are experienced with electronics you can replace the large electrolytic capacitors. If not just flip the switch but be ready to turn it off quickly if any strange noises or odors occur.

Good to know, thanks. I’ll give it a shot this weekend. Wish me luck.
