I've seen two versions of the Cadet schematic, the single box and the two-box version. Both use the same resistor, 6.8K, but the FB capacitor is 100pF on one version and 390pF on the other.
Just a wild-*** guess, but try changing the resistor over to about 4.7K and the cap to about 1.5x its current value. This is connecting it the 8 ohm tap on your new trannie. But if the amp is working fine with the existing FB values just leave it.
A 15K resistor in parallel with the existing 6.8K results in close as damnit to 4.7K. Easy to try and minimally invasive. Maybe try this first with the existing FB cap and call it a day.
