Russian germanium are easily accessible, there’s a shop out of Russia that’s sells on Amazon…it’s a bit of a wait but not awful. Also get one of these AITRIP Transistor Tester GM328A Voltage Frequency Waveform Meter LCD Display R Inductance Square Signal PWM Diode Capacitance Generator Multifunctional sy Operate Resistor with Acrylic Case https://www.amazon.com/dp/B08R9NPZRZ/ref=cm_sw_r_cp_api_glt_i_K7RMZX02VT6E22AXSENN?_encoding=UTF8&psc=1 It’s real handy for testing transistors, caps, etc… It’s also cheap and I’ve found mine to accurate. Bojack is horribly consistent at being inconsistent. I believe the 1N34A’s I got from them were just 1N4148’s silicon’s.
