The Champ 5F1 starts its life as a turret board. If you're not familiar, these were very common in the 50s and 60s, where axial capacitors and resistors were lined up on the board. Why I wasn't alive back then, I assume this made electronics easier to fix for the visiting repairman, who could simply look at the board and see where the problem component is and replace it easily. The use of these faded as electronics were more commonly replaced rather than fixed. You can easily find one pre-made for the 5F1 on Ebay, Watts Tube Audio or buy a black FR4 board, drill the holes and affix the turrets yourself (It's fun!). You can get the tools to do that at Watts Tube Audio as well... I encourage you to support them, they are a great small business and a source for myriad board designs.

Getting all the wiring correct is important, and a little tricky as there isn't a ton of room once everything is in place. I highly encourage you to visit Rob Robinette's fantastic page on the Champ 5F1. It lays out all the parts and their purpose, as well as optional parts. Rob is an awesome guy. I once messaged him to donate some funds for site maintenance as I was building one of his designs and he told me "just buy yourself a few beers, I do this because I love it". Also on the page are various guitar mods, headphone circuits, car tweaks, you name it.
Next we need a cabinet to drop this puppy in. I had one custom made for me by a Jim, who goes by tubeampcabinets on Ebay. The work is phenomenal, with Spalted Maple and Purple Heart accents. I highly recommend you reach out to him via Ebay to get yourself a nice cab yourself.
