I have them both and feel that the 7308 tube offers most of what a CCA has at less money, but as always, tubes are very system dependent.
Difference between Siemens CCa & 7308
Any significant differences between Siemens CCa and 7308 tubes of the same era? I know the CCa is highly regarded, hard to find and expensive. Seems the Siemens 7308 is a bit easier to find and slightly less costly. Does the 7308 give up much in performance? Thanks!
