I had a Benz Ebony H and it is one helluva cartridge... Seriously recommended.

Viiu, I have to disagree with your advice to a relative novice regarding buying tubes on eBay. eBay is a quagmire when it comes to tube buying. I have been ripped off more often than not, and I have stopped using eBay as a source. Perhaps you have knowledge and experience regarding the sellers that allows you to pick and choose, but I would advise this poster to pay a few extra bucks and buy tubes from a well known, well liked vendor.

Ebay is a crap shoot but I do have a tester and I wouldn't recommend anyone buy tubes without one. You're also correct that experience helps. I consistently look for tubes from vendors who have test results that are similar to mine. Certainly buying from a known, well respected tube seller is the best option for those without a tester.
