I need help on Cary SLP-05 tube roll ...


Hi all,
I'm newly own a SLP-05 and just hunted some NOS 6SN7s:
- 4 matched Sylvania 6SN7GT tall glass
- 2 matched Kenrad NAVY CKR-6SN7GT black glass
- 2 matched Sylvania JAN-CHS-6SN7GT VT-231

Please help me pick 6 out of them for tube position 1-6
(headphone tube 7,8 can stay with stock)
- 1 and 4 are left channel gain buffer
- 2 and 5 are right channel gain buffer
- 3 and 6 are L&R balanced input buffer.
Which buffer is most sensitive to tube roll, gain or input ?
I'll use the unused 2 tubes for my CAD120S driver buffer

Thanks

I replaced my rectifier tube with Mullard GZ34 Blackburn along with 6SN7s so I can't tell how much this rectifier tube help tuning.
Thanks
Homosapien, what improvements did you hear replacing rectifier? What rectifeir did you add?
I replaced stock rectifire tube with Philips Miniwatt metal base - very expensive, but the result is great improvement in all aspects.
