When searching information about resister noise I found this webpage:

Interesting technical tutorial on suppresion circuits and causes of EMI. Good when DIY suppression filters.
My Krohn Hite 4500 oscillator shows too high THD at roughly 0.4 % instead of stated 0.001 % at 1 kHz.
According to the schematics and test flowchart the voltages seem to be OK.
Does somebody had this model repaired and and can give a hint for this failure ?
Also a complete service instruction...
