2 Meg across the 3.3uF remove the peaking. Nevertheless the circuit 
still has
problems with its time constants. Weird things happen if you let the 
transient analysis
run for a minute simulated time  (must increase n cycles for the source).
Probably I'll accept a higher low frequency corner for now to get reasonable
simulation times.

Remember, that is not a publication but a snapshot of work in progress.
Some part values may be just the result of "what happens if..." experiments.
Or that I have a large bag of 3.3u foil capacitors and would like to use
them up first, if possible.  :-)
