Default Looking for ideas... 50W OPTs

Hello all!

I have recently acquired a PT(2x6,3V 3,5A) 340V and a bias winding and two OPTs 50W UL 3.5K, they were original intended for a EL34 PP, but as I already have such a amplifier I am looking to utilize some of all the parts in stock

I got
16x CCCP 6P45S (PL519 eqv.)
2x Mullard QB3/300
2x Phillips QB2/250
2x Phillips PB2/200

I have been thinking about 6P45S SE, but OPT could likely do more. Maybe 6P45S PP, just need some extra filament supply.

If I wanted to go SE with the 3 last mentioned tubes, I think the OPTs are too small and extra filament supply is needed for sure, and properly also new HV supply.

Ideas and advises on what road to take is welcome

Kind regards
