Re: Yet another 'replacing carbon resistors with metal film' question....


Jared, is this the PG502 pulse gen or PG506 calibration gen?

if a CAL gen with high speed edges, I suggest to NOT change any resistance or cap in the fast pulse output section

In our work, since 1970s, carbon comp and carbon film resistance fail with

a/ over dissipation
b/ high-voltage
c/ mechanical stress eg on leads

They dont fail during normal use, very reliable.

Just the ramblings of an old retired EE

Bon Chance
