Alright tube from my last point looks so dead on my tester, in the amp it plays but hiss is stronger now. I may have killed it trying to rejuvenate it but it was pretty unstable and noisy before.
So this kills the '60 and '61 pair of white print valvo cca I have (the '60 tube is still alive and kicking).
Then I found I had a single heerlen 1971 E88CC white print 7LG froim waaay long ago and decided to try to match it with a Valvo CCa white print '74 7LH which means swapping my other pairs of white print valvo cca the '60 tube ends up with a '67, the 71 E88CC gets a 74 Cca, and a 72 7LG CCa gets a 70 7LG.
Listening to the mixed bread pair of E88CC and CCa 72/74 and tubes are exactly the same, same sound completely quiet lovely sounding. Gotta listen to the 60/67 pair now to see how it works out
