"Can be build on the board w/o cutting tracks.
(Just swapping the op amp doesn't help anything, as the 22k is the main noise source. )

If "stereo" is meant as "mono in, stereo out":
The driver amp could drive 2 tranks, just add another 100Ohm (R281) for the second tanks drive coil.
Add another recovery amp (as above).
One supplies R212, one R213 (= Faders for reverb level left/right. )"
