Abill, The remaining good tube was checked by Sophia and tested as new. I purchased a matched second tube and they both were then sent back to Charles to resume his planned comparison.
They are actually an additional pair that I have.
I am using my other pair here, now. I am very happy with them, and was not looking to get rid of any. You already have a pair of RP's?
The amplifier that was tripped by the Takatsuki's was the Wavelength?
