Hi, & thanx for posting the pics of the 3D Mic & the Infra Bass. I've been interested in the IB since i first read about it in a hifi mag in the 80's. I bough the plans for it from Wilmslow audio, which i still have. I never got round to building one though ! Is the IB still working ?

I wasn't aware of the 3D Mic until now. That seems quite remarkable too.

I noticed that your name is Stephen Holliman, so i'm "presuming" you are related in "some" way. If you are, in what way ? Did you inherit both items, or aquire them in some other way ? If you could tell us more about GH's life & work etc, that would be appreciated.

I've contributed to several threads on here about GH's IB. If you do a search on here you should find them.
