Unfortunately no. It was a while ago - early 1990s. But it was very DIY and easy to describe...
Two sheets of (I guess) 3/4" wood sandwiched the bicycle inner tube. This upper sheet was topped with 'hollow' concrete blocks. The ones I used were rectangular. Two side by side formed a square large enough for the Rega to sit on. I think three layers of these blocks put the TT high enough for normal use.
TBH the blocks were a bit heavy - the blocks had to be broken down to re-inflate the tube every two months or so. The result was certainly worth the inconvenience. It seemed to make the Rega 'quicker' as well (transient response), which I guess could make sense in terms of reduced mechanical feedback and cleaner upper bass/lower mids.
The speakers I had at the time were the first of B&W's revised 801, the Matrix, with an active electronic filter that extended -3dB bass to 17.5 Hz. So I needed to come up with
something 
I wondered whether substituting some kind of rubber ball - three probably - would have been a more lasting substitute than the tube, but never tried this.
I recently saw almost exactly the same idea (link below), and learned I'd only achieved half the solution!
