6550 tubes:
Other guys at Aa told me that the best option would be a 6550 fying c tube from Svetlana (St. Peteesburg plant), since the regular svetlanas are really sovtecks relabled from the US importer. (????).
The said that the GE valves are not good at the frequency extremes, and the Tungs are the best but pricey.
Any comments?
