If you have room for three tubes, my suggestion is to use a 12BH7 grounded cathode feeding into a 12BH7 long tail pair.

I only have two tubes, the third is the amp stage prior to tone controls.

Line IN>Stage1>Passive Tone Control>Stage2>Stage3>7591A

Stage 2 and Stage3 are the two 9 pin sockets for the drive splitter.

I assume that your suggestion is to use 1/2 of a 12BH7 for an amplifier section and a full 12BH7 for the splitter. 3 total tubes for a stereo configuration.

I will look into your suggestion for a future project.
