I would talk to Mark O Brien at Rogue. Who would Know better? I just re tubed my 99 with Electro Harmonix, and they are micro phonic no matter what I try. I ended up sending my unit in for the Magnum upgrade, which will include new tubes...
Rogue 99 Mag re-tube Q
I want to re-tube my Rogue 99 Magnum and am unsure of what my choices should be. I know what I'd like to hear but I know jack about getting there. I listen to a wide range of musical genres and prefer a well defined, rich and wide soundstage at low to medium levels but want the shoot out the lights punch when needed. I'm looking for a do it all set up. I've heard that other Rogue owners like to split up the tube pairs so as not to attenuate the shortcomings of one tube type. Price is an object but for 4 tubes I think I can afford almost anything except maybe NOS TungSols or Mullards. Any intelligent thoughts are appreciated.
