Depends on how much gain you need.
Did you have too much gain
with the original design?

I would use it as a trannie myself.
If you have the right gain then I would wire the
LL1660 in 4.5:4 (Alt S with Pri & Sec reversed).
If too much gain then Alt T reversed (4.5:2).
No output resistor or cap needed.
Just Cathode battery, Grid Stopper and Trannie.
