Wiring/stray capacitances in RIAA network

61.12.0.102

Hi Inmates

I've searched the archives, but I can't find much on the subject of stray and wiring capacitances when determining cap values in RIAA networks.

Is there any rule of thumb when assigning a value for strays? Morgan Jones' "Valve Amplifiers" quotes "a few pF" for strays, which isn't much help. Should it be based on the total length of the wiring used in the network? Or should a rough figure, eg. 5, 10 or 20 pF be assumed? It seems a bit futile to aim for accurate cap values in the network when the strays are so difficult to determine.

Any help would be appreciated.

Cheers
Doug
