+[[Tunnel diodes]] are getting hard to find, although some types are more rare than others. Many Tektronix oscilloscopes use tunnel diodes in their sweep trigger circuits. When these diodes fail, the entire instrument is useless until you find a replacement.
 If you cannot find the Tunnel Diode you need, it it sometimes possible to use an alternate type. This page describes modifications that were performed on a Tektronix 547 sweep trigger circuit to use an available 4.7mA Tunnel Diode in place of the impossible-to-find 10mA original.
