Hi fellow Aune T1 owners, this is my first post ever anywhere.
So I turned to tubes (we call them valves) and did lots of research and then looked around. Seems I got lucky first time as I bought a VALVO PCC88 with D getter and waisted glass from 1957.
With good recordings these two are amazing. Everything is there, wide holographic sound stage, tight bass, controlled highs but the midrange is stunning.
Welcome to the forums and thanks for the very nice read. Seems like you hit the jackpot with that tube. Appears to be exactly what I'm looking for from good tube. Description fits my 7308 amperex, which has awesome natural controlled bass and very holographic sound stage. With that kind of tube you don't necessarily need any rolling since it already brings the best out of your T1. It's time to enjoy my friend!
