can't find the notes for a minimum loss pad, anybody who remember

values? It should be easy to calculate, but I am not in the mood for

Here. Hot out of the math package. Assuming I know what I'm talking
about it's an L with series 43.3 & shunt 86.6 (theoretical). Should be
6dB of attenuation.
Faint bells ring... 43 ohms is a standard value, and 86.6 is pretty
close to 100 paralleled by 680.
For testing 75-ohm TVI filters in a 50-ohm system, it's very handy to
make up a pair of those pads as inter-series adaptors.
