RE: Fed up with old stock 12AX7 RCAs dying or becoming microphonic!

The RCA tall plate are a shame they go microphonic or are noisy. I had too many noise issues with NOS RCA 12AX7 tall black plate. The black plate just do not last long with regard to noise.
I find no difference in sonics with NOS RCA 12AX7 tall grey plate. Few are noisy. I would not even consider any RCA 12AX7 used tube.
I did not care for Genelex reissue, but my amp is very revealing to 12AX7 preamp tubes. The amp is ultra clear sounding. Anything less of an amp limits the 12AX7 performance as the tube sonics become slightly smeared over.
