As ZM suggests, go for BL here.

Note:
The grades here are not a tolerance range but rather a range of Idss values. Idss is the drain current when the gate voltage is zero with respect to the source, i.e. both grounded.

After a longer hearing I can say the BA-3 frontend with crippled F4 has a clearness and a articulation I first heard in a similar way with F1J......

it is not a sweet sound ....

But I still can try P3.....forth and back.....

I converted the article to PDF, zipped. Hope it helps. Mods, if you consider it inappropriate for any reason, feel free to remove it.

Do my eyes deceive me (steady boy you're in uncharted waters here thinking for yourself) am I missing an input or is this a single ended design.

This remark is very intriguing, well worth a try, imho only doable if you have a distortion meter:
Quote:
Adjustment of P3 will bring the second harmonic out, and as you turn the wiper toward the Source of Q1 you favor the positive going waveform. When you turn the wiper toward the Source of Q2 you favor the negative going waveform. Favoring the positive going waveform is possibly preferred – with proper speaker polarity, this mimics the acoustic character of air.
