I have just found out that my oscilloscope contains a tunnel diode, and apparently these are incredibly rare devices, my Solartron CD1400 has a JK10B tunnel diode, and I can't seem to source a suitable replacement, I would be very keen if you could cover the topic of Tunnel Diodes, their testing and replacement and also if there is anything that could be used instead of a tunnel diode to create the same effect
