This is an on-going task maintaining a large fleet of rental backline gear. Just last week I had to replace a Littelfuse '345' fuse holder in a Peavey Classic 50 Combo amp, and the week before, a different Littelfuse '345' fuse holder in a older Fender Twin Reverb. The current Fender Twin's, Deluxe Reverbs and others are using the 'current' Littelfuse 345 Series fuse holders (P/N 0345LF8H), whose fuse cap does NOT fit these older Littelfuse '345' fuse holders, as the mechanical design is quite different in the throat and flange details. And, I can't find any data sheet that mates up with this older design on their website. Here's images of the current 345 Series holder & 3AG type mating cap (also uses a 5 x 20mm cap).
The first two images are P/N 03453LF8H....shock-safe 3AG Fuse Holder & Cap. The next two are also type 345's, and in getting the data sheets ready to add to this post, I think I found the missing information on one of the type 345 data sheets in my files. I haven't yet tried to purchase any of the fuse caps for those, until now, and hopefully this exercise will lead to being able to get replacements.

On page 3 of the second datasheet, it lists the mating fuse cap (knob only, as they call it) for each '345' holder style. So, my mystery unfolds. Now to see if I can still purchase those parts. It gets old not having a supply of all the different types of fuse caps in use on all of the gear in our inventory, and, while it does make me more money having to pull a chassis from a cabinet and replace an entire fuse holder for lack of that silly part, it still is a PITA.
First attempt to find a fuse cap for one of the 'older' 345 style holders on Mouser is unsuccessful.
