funny, i can't get the server to respond. maybe there's a router problem or something.

here's their listing at network solutions. don't know why i can't reach them.

hmm... I'm not sure how you would get around whatever that is preventing you from seeing the page. Well here are a couple of photos from the first page.

Works fine from here and has since the first few moments of the first post.

Note that the site wants to install a language pack, which I declined, but depending upon your o//s or browser settings it may come up as something different. IF there's a message, read it carefully as it may actuallybe getting through.

You can try to ping the site from the command line to see if anything is getting through.

Very interesting site though.

It looks like the guy is making plasma in a tube with an induction heater.

Thanks very much,,, this is one of the coolest things I've seen!!!

[popoahi]

where do most of you get your tubes from??? like 12ax7, at7's, 6L6', 7025's,,,,,

like who sells the best quality tubes like these I've mentioned??? I can get most of them from a couple of local guitar shops here but
I'd like to know where you guys recommend to buy them from???

popoahi

[popoahi]

Has anyone taken a look at some of the equipment in use?

Some of that stuff looks like an engineering nightmare (or a marvel)
