Papa told me: the FG-50S and PASS SIT 1 transistor will have the best combine if I connect 32 ohm tap primary with 25VDC at 1A bias
Many thanks..........Papa

Thanks! Using tube buffer is a good idea but I think the tube with output transformer is better

You`r right ,
just to add , at that specific schematic good 600ohm SE-OPT dedicated for 6C33C tube will do the job .

Teflon capacitors have small uF value and cost is opposite , Mundorf paper in oil ?
For cheap experiments try and nice quality maybe bi-polar Muse ?
Price = 1 pcs is less 0,50$ only...anyway you build without

There was a pair of FG-50s on the swap meet here on diyaudio, but I'm sure someone snatched them up by now.
