Rebbi,
That is great. Just bought my 6CA7-Z from Rachel at Grant Fidelity, plus past 300Bs and CV181s. Fabulous to work with them. You will likely like these tubes. Recommended by Israel Blume for his 300B amps amongst others. Again, best of luck with everything, I'm really happy for you, rooting that all works out the way you would like.
