Hey RATs:

Can anyone recall a "classic" commercially made amp that used a choke
input?
Not a guitar amp, but hifi. Been sifting through schematics but haven't
happened upon one yet.

hey-Hey!!!,
Sure! One would be the Altec 1570. Full bridge of 5R4's feeding the
Peerless 17266 choke, terminated with a small oil cap 8? uF.

I think some of the other IPC/Altec amps did it too. Fuzzy memory and
all that, but 1520 and 1530 may also have LC filters.
