Skip,

Do you have experience with the RCA 7591 tubes? Are they considered a superior tube compared to JJ or other brands like Westinghouse or Sylvania?
Just want your overall impression.

Thanks 528hemi

7591 tubes

528hemi- All vintage 7591 tubes are excellent quality, and I don't prefer one brand over another. Current production tubes are a different story...... I find that many (heavily hyped) new tubes are very inconsistent, quality-wise.
