I just recorded and uploaded two files on Soundcloud: the first one for the Classic and Spacey delay (with a bit of Medium A reverb), and the second one with the Hall and Concert hall reverbs.
Bassline (saw osc with filter turned up, no internal fx) from A4Mk2, Doctor A as a send effect (with kill dry selected) on Model 1 (no filters/EQ), recorded with H4n on the main stereo outs.
Within each section, I play with feedback/decay, modulation, level, filters; in the first file, I also modulate the amount of delay sent to the reverb.
Delays Classic and Spacey + Reverb Medium A
Reverbs Hall A and Concert Hall
Edit: Headphones strongly recommended…
