alternative for LL1660 18 ma

80.57.25.215

Hello
I have a LL1660 (18 ma ) (SE to PP) which can be used for phasesplitting ( for example with ecc99 ) to drive 2A3 or 6B4 in PP .
As an alternative I could use a 1540 input transformer for phase splitting and a 1660 PP version as interstage to drive the 6b4 tubes .
Which configuration should give the best results (ecc99 as driver tube )
thanks
johan

I prefer the input phase splitting approach of the two. This is for two reasons. The first is that without the appropriate Faraday shields designed into the transformer, the phase splitting interstage transformer has limited high frequency extension. There is a version of the LL1660 (called the LL1660S) that has these shields, but there are no versions of the LL1692A, LL1671, etc., with these shields. Second, the phase splitting input transformer provides for both balanced and unbalanced input interface.
