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

Late night posting with one eye open I guess.

Nice link Tvad. I have 4 pairs of the early gray riser Siemens( some call them gray plates) and all have the codes on the glass but one.
But they are ECC88 not CCa, although CCa are said to be the pick of the litter from ECC88.

Semens & Halske E88CC

Characteristics:

- double stage getter

- AØX ≠XX code on getter support

Comment:

Quite rare.

That is the info from the website. I think a bit of an oversight as most I have seen that have the codes on the getter support are the silver riser.

I have 8 tubes with the AØX ≠XX code. 7 being gray riser with code on glass and 1 gray riser with code on getter support.

Go figure!

I also found the ECC88 gray riser to be better then the later CCa silver riser. YMMV

This is my favourite tube from the 6JD8, 6922, 7308 family.
