Best 6550's for ARC VT-100 MK3 amp- SED; Tungsol??

Sutts:

The EAD's are just rebranded and marked-up run-of-the-mill tubes -- EAD is doesn't manufacture tubes. Don't waste your money. IMHO, The best sounding 6550/KT88 in current production is the Penta Labs Shuguang solid plate KT88, which is designed after the reknowned Genelex KT88. Feel free to e-mail me for more details.

many thanks guys- great responses- I may e-mail a couple of you for more info...

The winged C 6550's are stock on the VT-100 MK3. Since that amp was voiced with the winged C thats the tube I would go with. G. Garfield

I have used SED and Tung Sol 6550 in my VTL ST150 and I found the Tung Sols to be more to my liking. The Tung Sols had a firmer bottom end in my system. The SED sound was more open and airy than the Tung Sols but not by much. I felt that it was a good trade off and have stuck with the Tung Sols. I do want to try the Shuguang KT88-98 but that will have to wait a few years untill the Tung Sols wear out. Rolling output tubes gets expensive!
