I have been listening to my ST70 with the 6550 for about 2 months now. Just before I tell you what I think about the sound of 6550 compare with the EL34. I have to warn everyone; once I listen to 6550, there is no way to look back to use the EL34 anymore.
The 6550 sound so much warmer and have wider soundstage especially I am using the ST70 to push my JBL horn. I can listen to saxophone and jazz all day long without getting sick.
Now I have 4 RCA NOS EL34 for sale Anybody interested ??
Zx, one thing I suggest you to try is using 12bh7 on the 2 outside tubes. The change is noticable and make my ST70 sound even sweeter....
