Dude, you're competing with Russian and Ukrainian sellers who sell the same tube on ebay for a fraction of your price.

I am responding to egindin who mentioned eBay sellers selling at a fraction of what u are asking for. Those are graphite plates, given their price.

Which is the difference between Graphite and copper ?
Is not better the graphite for this kind of vacuum tube?
