Tunsgrams are the way to go though anything is better than the stock PS Vanes. Upscale audio has the specific Tunsgrams and it is a different tube type so you have to change a jumper on the amp when you swap the tubes.
I had serious buyers remorse until I rolled in different tubes. With the better tubes, it is a very nice unit.
