LL 1660 SE to PP : In secondary p5 and p10 normally connect to ( common) ground (schematic Alt V new )
Neg. bias supply has to come via lifted ground connection of transformer secondary .
Proposal for splitting ground connection in secondary ( so you can use separate bias supply for each connected output tube):
Lifted ground input Neg bias 1 to (5-2) to ( 8-9) to grid 1
Lifted ground Input neg bias 2 to (10-7) to (3-4) to grid 2
(---) = internal connection transformer winding , to = external connection
Pleas can you inform me if this will work ?
Thanks Jeremy
