Hi...your better off with the new old stock tubes - at least for your drivers - 6922 tubes.
I had a 200 and I liked the 6550 arc stuff - given the prices of the vintage stuff - but the 6922 tubes really made the amp sing! Changed its character a bit - which is what a good set (or sets) of tubes should do.
Discliamer - I am a dealer of New/Old tubes.
