...a phono preamp or related circuit where he's making the plate load part of the filter. An intentional filter is the only reason to use a choke in series with a resistor that I can think of. That would cut highs and boost lows, so it well could be part of an RIAA circuit. Could even be a good idea; fewest parts, etc. You would have to make sure that the circuit is pretty insensitive to variations in tubes, or use a low impedance tube like a 6CG7.
Crap, now I'm thinking about working on one, like I don't have enough to do.
