I have tested building a tube preamp with these AC mains protection options.
- no fuse, but a on/off breaker
- cheap fuse, no breaker
- Furutech fuse, no breaker
The breaker option sounded best and really does answer your question...at least in my 6sn7 based, tube rectified, voltage regulated preamp. Thus my earlier post. Avoid the fuse folks. I was taught this from the designer of Tube Research Labs amplifiers. Sadly Paul Of TRL passed away as he was a brilliant designer as well as a kind man.
