Never had that amp but did own Rogue RP-1 and RP-5 with ST-100.
I liked gold lion in the amp in 12au7 and 12ax7.
For the preamp the best tubes I tried were Brimar CV4003 from Upscale.
I also tried rca clear top from Vintage Tube Services (Andy) and found them a bit too hot up top in the treble.
Gold Lion proved to be good again in the preamp as well as amp.
Didn’t care for new production Mullards and Tung-Sol.
