長屏mc2 more musical and slower and hence better for vocal
Valvo 45 degree is more balanced than Mullard and TFK
Am using Valvo 45 degree short plate 12ax7 (coded I60 D0H) with Nagra PLL to get balanced sonic performance. I have collected:
- Mullard 10M Master series 12ax7 (good for instruments)
- Mullard mc1 with square getter and long plate (good for vocal)
- TFK smooth plate 12ax7 (highlighted in mid)
