Sorry for this insert, but I don’t want to open a new topic:
I could not cut a Darlington transistor into 2 pieces 😉 – so I used one Lectron block for it. It’s a common MPS-A13 (European equivalent: BC517) to test a circuit for voltages from 1.5 … 9 V for an AF amplifier stage. Low voltage amplification for e.g. the AM radio block #2454 (ZN414 / MK484 / TA7642 / LA1050 / … with Vcc= 1.3V max.) and a low-loss speaker connection (s. above) with a tapped coil transformer (medium impedance speaker and headphone socket) for best results and economic usage.
Best,
G.
