Siemens Halske versus Siemens Rohre


I am new to tubes and have heard that Siemens Halske tubes are much better than Siemens Rohre. I am wondering if this is true for 6DJ8 tubes. Often times on Ebay I see tubes advertised as Siemens Halske but the box in the picture will say Rohre on it. Should I completely eliminate any Rohre tubes from consideration? Thanks in advance for your input

The pair on E-Bay with original boxes sold for $510!

That's nuts.

With a little more homework and research two pairs of used, but new-testing Siemens CCa could have been purchased for that price.
I agree with Tvad. That price was outrageous for a pair. A nice quad for that price would have been more acceptable.
I have obtained a quad of cca's through the a'gon want ads, but other offers keep coming in including one for a pair of ANOS cca RCA label for $150 a pair. If interested - email me and I will refer you to the person selling. Joe
