Someone posted that when using a pair of LME49990 in the BAL/SE stage that they will oscillate. He says to use 100-220pf styroflex or silver mica cap for feedback compensation when you use lme49990. When looking at the schematic I should place them across R22 Left 2.2K ohms and R23 Right 2.2K Ohms am I correct?

He states a different number for the right side so I just want to be sure that was an error. Can someone confirm?
