Yes, I understand the thinking behind that, but silicon transistors?
The only silicon I see is the BC 108 at the front. O.K. perhaps I've missed a bit of this whole story. If some of the germaniums have been replaced with silicons, that explains a lot - since silicons will have a much higher current gain - especially at R.F. - than germaniums! I'd replace any of those substituted silicons with the correct germaniums first, before proceeding further - as per my immediate post above.Al.
