paraphase bias wiggle again

I can do the 500k pot plan but the second method is above my understanding. I would need a drawing to figure it out.

Well this is what I was meaning. Whether it works with these circuit values or not I don't know - you might want to play around with them. I opted for a more-conventional cathode-biased AC-coupled CF stage just to ensure you get a good low impedance drive, but it probably is way overkill and it may need heavy attenuation (or not?), which what the optional 220k-2M2 is for. Good luck

Thanks for the schematic Tubeswell! I hope to give it a try soon.
