The HP sceme in the patent refers to an array of series and parallel
diodes to reduce noise.
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?
