5751 tubes in Rogue Tempest?

I used the 5751 on my Rogue M-120 monos with no problems,i tried the GE JAN 5751 and the RCA black plate 3 mica spacer 5751 and the RCA was by far the best of the two, the sound was warm,detailed and smooth the GE was bright and boring.I did not try the Sylvania 5751,the RCA sounds much better then the stock Sovtek 12ax7LPS that came with the amps.

I use 5751s in place of 12AX7's in the BC SET40. The 5751's has a little less gain and lower distortion.
Try and find some RCA triple mica 5751's. These are the best sounding 5751's I have found. They are hard to find, but worth the effort.

Use a 12BZ7 in place of the 12AX7. Rouge confirmed this is safe to do and the amp sounds way better. Much more dynamic and musical. Been running mine this way for more than a year. Got the idea from Cary folks who often do this on their amps.
