I'm glad you said enthusiast!
In my dim and distant, working as a TV Engineer, another fuse went in
first.
The same when I was in the trade but remember, we weren't
powering up sets that hadn't seen the light of day, let alone
power, for 20, 30 years or more!
Usually a Variac is used as well as the main smoothing, at
least, usually needs reforming so needs to be powered up
gradually.
I don't dabble myself but do follow a couple of forums where
most members do. It is surprising how often the smoothing
reforms OK - a bonus as you can't whistle up a replacement
from RS Components these days!
In fact, before even switching on, there is a visual
inspection and the suppressor capacitor across the incoming
mains supply snipped out!
