King Tubby Hi-pass filter effect...

Hello, I'm just wondering if there is any way to emulate King Tubby's hi-pass filter effect with plugins, or is it only possible to do it with electronics...?
An example I found: http://www.box.net/shared/aqdse74g80
(The effect I'm after starts at about 18 seconds in.)
I'm guessing the effect is due to a combinations of things, including tape noise. But aren't those filters inductor based, those built into the desk in the 60's)?
Apparently "...it was an MCI mixing desk that King Tubby modified, so it had things that the modern boards nowadays don't really have, like a high pass filter that made some squishy sounds when you change the frequency."
Whenever I try plugins, they sound TOO squawky or whistly and synthetic. Perhaps no one has bothered to emulate it, or have emulated a more modern equivalent of the effect.
Thanks in advance.
