Joe:
I hear what you say about not having the correct transistors: germaniums types.
Please excuse me if the next lines sound blunt: I am trying to help. I honestly believe that until you fit the correct types, you are really wasting your time and effort pursuing this further. As I said previously, silicon transistors generally have a much higher current gain at high freqs. than germanium types - hence, doing what you have done runs the risk of the whole amplifier going unstable at some high frequency. Of course, if you're happy to redesign the amplifier . . . .
