[QUOTE="fredeb, post: 938983, member: 13623"] Just be careful when using 6P3S or 6P3S-E in place of EL34 . I have a modified ST70 with fixed bias , my ST70 bias adjusting pots allow enough wiggle-room to adjust negative bias on grid to ~ -35V . So the operating point of EL34 and 6P3S are very different places . I'd rate a 6P3S closer to a 6L6 (not 6L6GC) . My recommendation for a current production EL34 would be JJ EL34L/E34L or Tung Sol EL34 , both perform very well in my experience . [/QUOTE]
