I have to beg to differ that this series of Astrons (the linears like the RS-35M et al) are all that 'reliable'. I have had to replace the LM723 (I think it is) regulator on a couple of these and hav

I have to say that I have observed RFI coming from my Astron RS-35M 'linear' supply. It is in the form of a pulse or 'buzz' at the line rate. It kind of low-level and is noticable on the AM broadcast

Brian, I compute the effective 'resistance' (X_sub_c) value to be only around 16 Ohms* for a .01 uF cap for the band where I notice the noise. This might be wholly insufficient to quiet this beast do
