"8A" reverb tanks?

[lars]

Did I miss something? All of the sudden, "8" size reverb tanks with the "A" low-impedance input have sold out worldwide. People seem to have gone nuts trying to gobble them up. Does that particular tank somehow create free beer when you plug them in or something? Just today I watched them sell out on Ebay in the 20 seconds or so that I found one listing for a few. I couldn't click buy it now fast enough, apparently. Other sites all say, "out of stock" or "that page doesn't exist". There aren't any on Reverb.
They're just all of the sudden gone and if one does show up, people frantically buy them before you can even look at the listing.
It's weird.
