Chassis Layout Advice

Yes, I think the layout problems are much better addressed in your last photo. RCA inputs near input tubes is best for signal, and switched IEC near power transformer good. If you are going to put the speaker posts on the top plate, I would place them just behind the output transformers.

I think this layout keeps all signal and power wiring as far apart as possible, and you also get to see your glowing tubes when in use, rather than the output transformers 😉

See Jones regarding magnetic interaction of transformers. He shows where the most flux leakage occurs from transformers. Spacing you have between transformers looks good.

Enjoy the build!

I agree that's a better layout (if you're thinking about the wiring), if you're thinkig about looks...not so sure. There's another option- output transormers in line with the rectifier. Try and see what you like best.
