Both amps corrected, just need to find a day that I can spend some time getting them warmed up and biased, that day was not today, and won't be until next week likely.

120v in, ~.32v across source resistors, .8A draw from the wall. 5mV of dc offset. Heatsinks are about 100F 37C with the top on. Music plays.

Would a 2.5A slo-blo fuse be enough? I think Papa calls for 5A in the article but that was for stereo? I'm not sure.

Smaller, in this case, is better than too big, but expect to lose a few. These amps can draw lots of current. Have spares. You already have two pieces of the ohms law equation, voltage and watts. You just need to know the total peak current draw that's safe.

Pegs my 15A meter at start up. Would like to avoid installing a CL30 since it's pretty cramped. Doesn't seem to blow the fuses, I think I'll just keep in the smaller fuses.

400, and I have some CL30s but I didn't use them on my normal F5 and it was just fine.
