** The falling out I recall was in April or May of 1983 and coincided with
the publication of the ETI Series 5000 graphic equaliser. This project is
memorable as it was clearly published without the prototype ever being
completed or tested.

The installation of 1kohm resistors in series with the supply pins of each
op-amp reduced the supply to those ICs to about +/- 4 volts - hence they
could barely work. The unit utterly failed to meet basic specs.
It proved impossible to get Tilbrook on the phone about this to have a
correction published and nobody else at the office could even see the
problem or gave a hoot.
I note that Altronics are STILL selling the high power speaker protector
kit that Tilbrook designed in 1982, which also does not work. I did speak
with him about this and got stone walled and fed a load of bullshit over the
phone - seems this was the guy's standard way of dealing with all criticism.

** AFAIK - Tilbrook parted company with Harrison and ETI prior to AEM
commencing.
Tilbrook used to be listed as ETI Technical Editor, his title seemed to
change to Associate
sometime in late 1983.
