The smaller CRTs reserved as secondary screen of "Lan" play. Still, that 13" TV a good holdover to enjoy your retro consoles.
Yeah, I really miss gaming on CRTs. I picked up a 30-something-inch Sony Trinitron off the side of the road a few years ago, and aside from testing it to make sure it works I haven't had the opportunity to use it yet.
I've been growing fond of the bubble screens though. Back in the day, getting a flat screen was awesome and you didn't want to go back to a bubble screen. But these days, it's a nice throw back if nothing else. Also, I think it helps to hide minor geometry problems (like when the corners pinch). At least with Trinitron screens, the screen is only curved in one direction so it isn't a true bubble screen. Don't get me wrong, I'm not getting rid of my 27" Wega any time soon.

I do not see any diodes for one direction to prevent any possible cross feedback. Never have an issue of a signal too loud or distortion feedback with an RCA YPlug converting stereo to mono on the PVM or 1701. Some game manuals state to use just the white connector for mono TVs, I think some game sounds lost if leaving the red jack disconnected.
That's interesting, I'll have to ask about the diode on another forum, but I'm pretty sure you don't need it. You're mixing the signals into one, and the resistors will correct the impedance. So, yeah, the signal is just being attenuated. Mixing the signals with a Y cable wont make the signal too loud, though. Actually, quite the opposite, it can lead to signal loss.
Y cables are for splitting, not combining or mixing. But here's the thing with electronics, you can hook things up WRONG but it will still WORK. That doesn't make it OK, though. Equipment has tolerances and sometimes protections built in for that sort of thing. So sometimes you're OK, but you're kinda rolling the dice when you hookup something wrong that nothing will be damage. So combining two audio signals with a Y cable might "work" in most cases, but I'd rather be safe with my equipment. I still can't find such an adapter for sale any where, but making one is no big deal.

That's actually a giant pain in the ass, I wish TVs wouldn't do that. It makes it hard to diagnose problems. It's probably a thing because VCRs had only mono outputs for the longest time. It was only the last stretch of VHS that VCRs had stereo (or dual mono) outputs. Or, at least, that it was common.
