an Adcom 545II?? Took the lid off to look at the inside for obvious issues before putting it into the system and there are many tiny allen screws which were very very tough for me to undue because of my peripheral neuropathy and if I can leave it off without issues besides being electrocuted by putting my hand inside then I will leave it off.
Follow Ups:
when I worked in a semiconductor fab as an equipment guy, I was REQUIRED by good practices to replace every fastener I removed.
One buddy was working on an RF generator, used to generate a plasma in a tool, when an idiot dropped their (stainless steel) tweezers INTO and ON the circuit board, reached in a plucked them OUT. No smoke, flames, zaps or ANYTHING.
Other people, leaning over active, high power RF circuits have been medically damaged by so doing.
At least SS doesn't have the wacky voltages common in tube gear.
Too much is never enough
I had an amp fail in a blue flash of ESD due to the accumulation of dust inside. And my amp had a cover on, just with lots of vent holes on top that I didn't keep clean.
Circa early 1960's one of my brothers and I each made a 5 tube AM radio from a kit. The circuit was very common with minor variations. This versions was a table top radio with a plastic case 60's looking case, a volume knob and tuning dial.
One got regular use in the living room. For some reason, I think after replacing a tube or futzing with the trim caps or something, whoever reassembled it left off the fiberboard back. Kinda like the lid in this thread.
One day I went to pick it, reached around the open back instead with my right hand got I gabbed the bottom half of the circuit. I forget if it was wire to wire of if there was a circuit board. It must have been "on" at the. My hand was "glued" to the it my muscle contractions. I yanked my hand off, which wasn't easy. No lasting damage, but it was very painful.
I highly recommend avoiding conditions that would allow this to happen.
Seriously.
SmokeTest--in this case I was almost the source of the smoke!
People sure can be stupid. Hire someone to put the cover back on, or ask someone to do you a favor. Or accidentally kill yourself.

Ah yes, good old Murphy...
Sorry. Try it now.

My Sherwood come without a case and it has around 500 volts floating around in there. As long as you're careful and it's only you in that area why not.
Or just leave the case on without the PITA screws. Do you know how many units I had like that because of various intermittent problems. At one time I was like a Indy 500 pit crew undoing those screws.

Leave it off.Check out the last paragraph in the link below.

Be certain to have a full salt shaker nearby, 'cause you'll need more than a single grain of salt to deal with some, not all, of Pierre's (Mapleshade) fables.

Please put on the cover. You might accidentally get hurt. Murphy's Law almost guarantees something bad will happen.
For years I have placed the cover on my tube preamp without inserting the screws (for easy tube swapping) and put a VPI brick on top to minimize the possibility of vibrations. Do something similar.

For some 3" tall 5" round patio bricks I use some rubber. It is thick rubber, so I just leave the rubber under the brick.. not gluing it.
I leave the cover off my tube preamp. It would take a great deal of effort to stick your hand in unless you pulled it out and it runs cooler.

x2 If it can just be placed on there, why not?
Just put the lid on without the scews. I do that with my tube preamp so I can swap the tubes without removing the tiny allen screws (many) every time I want to swap a tube.
