The voltages for the other transistors were measured WRT B-ve because those transistors are NPN, again it makes it easier to interpret for those types.

Cheers Lawrence. But I think I've finally figured it out, See my above post.

Yes but if your measurement of 9 volts on the emitters was WRT B+ it means 9 volts across R26...
