I was walking past a rag and bone shop when I saw a big box of Mullard CV4014s, and GE 5650s for sale. They were cheap, less than a dollar each. So I am now the proud owner of 10 of these tubes, but have yet to find an audio use for them. No much luck finding any audio application on the net, so obviously many had tried and said yucks, or it is an undiscovered gem ( is this even possible ?).
With its high mu in triode mode of the CV4014, it may be a good driver for two stage SE amp.
I have build a 6AG7 ( penthode mode ) RC coupled to a 813 triode mode amp previously, and it sounded quite good, though not as good as my 6J5-2A3-GM70 amp.
So anyone else with prior experience with this CV4014 or 5650?
