**Only** way to use this amp is using a 1:1 isolation transformer, such as:
187E12 Hammond Manufacturing | Mouser

This "Decca" amplifier is one more of the long list of infamous cheap guitar amps, also sold as Silvertone / Airline / Valco / etc.
Actual brand printed is just a label inside they are basically the same.

If you want to build a Champ, just do it ... elsewhere, not worth here.

I'd use as-is (obviously with the isolation transformer), sound is cute.

I think this may become a speaker cabinet.

My wife brought home an old Electrolab guitar amp several years ago that sounds similar to this one, except it had another tube, I think it was a 12AV6 for more gain. I added a Triad N-68X, changed most of the caps and it worked. I plugged in my pedal board and let it rip. It took about 2 minutes to shred the original sun dried speaker cone.
Tubelab, it's 5 year mission. To explore strange new tubes, to seek out new circuits and topologies, to boldly go where no tube has gone before......
