The tube has no voltage on the plate. It's obviously all under the cap which even turned upside down, still would require intentional poking to be contacted, assuming one uses a decent cap and not a raw wire or uninsulated clip. The fear of plate caps in 500V or less devices is common, the reasons defy common logic.

I don't know why anyone would argue this point. Using a device with 400-500V outside the chassis is incredibly stupid in a family setting. Even my old ham gear - most of which used HV tubes with plate caps - was never constructed in a way that would allow access to the anodes. To do otherwise would violate simple common sense.

Incredibly stupid without a cage or cover in a "family setting" where some moronic family member chooses a low and accessible location to install the amplifiers, and also offers no instruction to "other family members" to leave it alone.
Yes OK.
If you can't achieve that, then you can't.
But in no remote form whatsoever is the use of plate caps, even in a
"family setting" (properly done) "violating common sense".
If you can't imagine other "settings" beyond your own, then you can't.
So this is why you'll just have to imagine that someone would argue this point. You do Not represent the last word on this subject, period.
"You do Not represent the last word on this subject, period."
You're wrong. It's not safe. Period.

It's not safe for fools, who ignore logical precautions, which it's clear you've included yourself amongst.
Seriously, how old are you?

Surprised you took the bait, but you did. Feel better now?
Or are you struggling with English grammar, again?
OK, so you don't like tubes with plate caps. No big deal. I think you are overstating the issue. I would want not a family member or pet going near ANY hot exposed power tube (especially a 211 or 6C33!)The original point (which is getting lost here) is that tubes with plate caps like 807/1625/6146B/6883B can and do make great audio tubes in DIY applications (which IS what this forum is all about). Having endured sub-optimum Chinese and Russian 6550's over the last ten years or so, I'm quite happy to not need to use them any longer. I'm quite happy to use genuine NOS tubes with much better overall quality control and longevity (not to mention excellent sonic performance!) The reasonable costs of these tubes is the icing on the cake.
