Indeed; I recently got an old one on eBay, and it is very big. The
capsules (or at least their grilles) sit on the surface of a sphere
approx 48 mm radius (using the Oktava MK012 cardioid capsules). I have
not used it in anger yet as I want to get it calibrated before I try it
out properly. My normal work has been too busy this summer to permit
time for my recording hobby, so for the moment tis mic languishes
uncalibrated and effectively unused. The output is type-II A-format
(LFD, RFU, LBU, RBD) rather than the more-usual type-I A-format (LFU,
RFD, LBD, RBU); but obviously just turning the whole mic assembly 90° to
the left (body vertical) will make the result effectively type-I.

It's been mentioned here before. The capsule spacing looks
substantially wider than the TetraMic's, because the capsules are
larger. This means that the HF performance will start to get erratic
at a lower frequency. You will also need to do your own calibration
for the A to B-format conversion (and be sure to mark the capsules if
you're going to swap them, so that you can put them back in the same
positions, otherwise the calibration will be out).
