The two 53KU's are now sold. Just the CV1079's left.

Re the CV1079's - I've thoroughly tested them again and tabulated & graphed the results. They've actually been tested up into the 807's region of Ia (83mA in AVO VDM). V1 managed it OK, with V2 chasing its coat tails.
So they are still for sale at 20 for both + 5 for P&P.

PS If anyone has an original CV1079 Spec &/or or Gm curves, (as opposed to the assumed KT8 equivalency spec), please let me know. I.e. "The Valve Museum" just calls them 'Sensible Equivalents'.

Regards, David
