Paralleling devices reduces noise. Why do you think otherwise? Noise will be reduced by the square root of the number of devices you parallel.

Just paralleling them does not reduce the noise! The 4 paralleled in the 5065 are to give enough phase deviation for the low modulation level applied. (150mv) The symptom was a fluctuating 2nd harmonic meter reading and coresponding fluctuations at the A7 TP2 test point. John I could not see the info you refered to?
