because he is Choky's friend
Play nice Zmuck 😀
A little something about the reason for a choke:

Inductors.
As much as we often try to eliminate inductance in capacitors and wiring,
inductors in the form of coils can be used to improve the performance of
power supplies. Placing inductance and capacitors on the AC line to
form filters will reduce both incoming and outgoing high frequency noise.
Large inductors in series with the transformer primaries and secondaries
can be used to stretch the duration of the charge pulse to the power
supply capacitors, improving regulation and reducing noise. Large
inductors in combination with multiple power supply capacitors can form
"pi" filters to reduce the noise on the supply lines.
Inductors are very useful, but they cost money. Their use in power
amplifier supplies is an indication that the manufacturer has an
unusually strong commitment to performance.

Doug ,
Thanks for the straight forward explanation , Interesting , how do you determine the value and size necessary ...

I use PSUDII to see if I can improve the supply.
Its a free download here: PSUD2
There are a couple of tutorials on the web.

Choky's Chokes ....... not some wimpy Metaldanske ones
naah ..... I just have sharp ears
here is a recipe for Real Man's ones ...... (or - if ya wish - Poor Serbian Man Chokes ) :
