Hello,
For my system: http://audioheritage.org/vbulletin/s...ad.php?t=11750
I just bought a second amplifier (the first is a Lectron JH50 equipped EL34) a Sonic Frontiers SFS-40 which is currently equipped KT88, but it can be equipped with the following references EL34/6CA7/6550/KT88/KT90/KT99a, your opinions and experiences on the best choice?
Thank you.
Stéphane
