No, actually it's from a guy on ebay who sdlls mostly old junk. I know what you're thinking but bear with me: a couple of months ago he offered a huge lot of ts 5998 on sale, with the specific mention that sold was sold, no warranty and he did not want feedback. Those tubes had pics and looked good so I chanced it at about 50 eur a pair. Frankly, I thought they would probably not be working and I was the only fool to have bid on them. Well, they arrived, nos 5998, no fakes, terrific sound and in my 337 now. I mailed him stating that I was very happy and would love to gice positive feedback but he refused, explained he had purchaseda gigantic lot of all kinds of tubes from a french army depot that closed down but didn't know about them (his actual area is militaria) and had no means of testing them, hence the 'sold as is' condition. By the time I received the tubes the rest of the ts had sold out, could have kicked myself for not having purchased more of them.
So, touch wood, I hope this one pans out as well. Before anyone asks, he only had one pair of the Haltrons. Will post pics when they arrive.
