RE: RCA 12AX7 Long Black Plate - Noisy compared to Long Grey Plate?

I've never had noise problems with RCA blackplates as input tubes in my Rogue amp. Don't remember reading that they were prone to noise either.
If you are using them in a phono circuit, they should be screened for low noise. That would be true of any tubes you would use in that circuit.
