Here is a quote from the other forum I mentioned by the guy who worked for Heybrook and designed the Heybrook TT2:
Just looked at the heading for this thread with some puzzlement. Heybrook TT1? As far as I know, there never was such a thing. The first (and as for as I know the only) turntable Heybrook produced was the TT2, so called because a) the first Heybrook speaker was the HB2, so it got to be a habit, and b) TT2 sounded better than TT1. If you really do have a Heybrook TT1, I'd really like to see some pics and a description.
It's from a thread by a chap asking for a new pulley for a TT1. No photos of a Heybrook TT1 were ever posted. Could you maybe get a picture of it?
