An echo that wanders and darkens: wow bends the pitch slowly, flutter jitters it faster, damp takes a little top end off each repeat, and the feedback path saturates readily. No sync — the real thing has a motor's own speed, not a tempo to lock to.

inputs
Down the left edge of the card, top to bottom.
○laudio
The signal to delay, left.
○raudio
The right side. Normals from l, so ONE cable in is the mono tape delay this always was — patch both and it stays stereo all the way through.
○time cvcv
Modulates the delay time, on top of wow and flutter's own wander.
○fb cvcv
Modulates the feedback.
outputs
Down the right edge, in the same order.
○laudio
Dry and echoes, mixed by mix — the echoes wandering, darkening, and warming as they repeat. Left.
○raudio
The right side, and it is not a copy: the two heads wobble INDEPENDENTLY. One transport, so the slow wow is shared and merely offset, but the fast flutter runs at its own rate on each head — which is what makes a stereo tape sound wide rather than like a mono tape on two channels. route and spread work as the DELAY's do.
knobs
Left to right across the face — the dials in the picture.
time0.001 … 2 s= 0.3 s
The delay time.
fb0 … 0.95= 0.4
How much comes back. High values repeat for a long time, and saturate more on the way.
mix0 … 1= 0.35
Dry/wet.
wow0 … 1= 0.3
A slow pitch wander — the reel, not the motor. Turn it up for seasick, seaside repeats.
flutter0 … 1= 0.15
A faster jitter — the capstan. Subtler than wow; it reads as a shimmer, not a bend.
damp0 … 1= 0.4
How much top end each repeat loses. Up for a dark, degraded loop; down for a brighter one.
routestereo · ping= stereo
How the two heads are wired to each other, exactly as the DELAY's is — and here the damping travels with the feedback, so a ping-pong tape darkens as it walks across the field.
spread0 … 1= 0
How far apart the two heads' times are. 0 is identical times — though never identical SOUND, because the two heads wobble independently whatever this is set to.
