Read this in a for sale add (Syrah)
"Here the original 417A/5842 has been replaced with a E180F/6688, which is the same tube used on the Cortese and Grange models. When triode-connected, the 6688 has the same transconductance as the 417A, but has a higher amplification factor and better linearity - and it sounds better too."
Are these a direct replacement for the 5842s or does the amp need modded?
Thanks Simon
