How two 6550 tubes compare


Can anyone define the sonic differences between the Tung Sol 6550 reissues and the Svetlana 6550 Winged C's, or if your just familiar with one of the two, what are it's sonic attributes?

In advance thanks.

Here is Camerio33's post with the proper spaces. I have no idea how your font or your message got the way it did but hopefully with the proper spacing membership here can help you out.

I just purchased an amplifier VTL ST-150 (latest version) in the used market. I have to retube the amp and I wonder if I should install tubes 6550C, as advised by the owner's manual of the company VTL, or if perhaps I should install KT88 tubes. Reading this thread, I learned that you also had an ST-150 and you have decided to "install KT88 tubes. I know what values of biasing did you do the tuning. Is what is the same as that advised the company VTL in the owner's manual for the 6550C tubes?

Thank you in advance for taking the time to answer me.
