First time tube rolling 12ax7’s. Sovtek WB’s, LPS, Doge (Select Shuguang), Tung-Sol Gold pin, Genelex Gold lion Gold pin. Ended up with SovtekLPS in Phono V18-19. Gold Lions in Phase Splitters V14-15. Believe it or not I like the Doge Chinese tubes in V16-17 Filter Amps. It’s just more articulate in high kids and highs over Tung Sol. Gold Lions have more punch in phase splitters. Didn’t try in phono stage but LPS have about the same gain as the Doge but more quite. I know everyone has different results, but as of today it sounds great. Thinking about rolling V100-102 one tube at a time in case alignment messes up. All tubes in those positions are Sovtek WB’s. Is that a bad idea?
