Also, what do you mean, "changing Q28 back and forth between a -O and a -GR"? (I didn't build my now-sold x0x, so I don't know what that means.)
The person who demonstrated this has every component with more than two legs socketed, yes. Personally I do not rely on socketed transistors hanging upside down...
Q28 is in the VCO, it has been debated whether or not this component beeing a 2SK30A-O, as in the original, or a -GR or -Y, has any effekt on the sound of the square wave in 303's and its clones. It might depend on whether or not you have matched the 733p's, I do not know. But there was a noticeable difference to my ears in his x0xb0x. I use an -O-type in my latest and a J201 in the first one. The J201 has similar specs to the -O.
