The original transistor would be a PNP germanium type (AEI - TR1A). I think an RF type, or at least designated that I believe (by Tri-ang). Original battery voltage was 9V. If you were to substitute that germanium PNP transistor with a modern PNP silicon transistor, what transistor would you select? Thanks.
