I am returning to the old days trying to use a unijunction transistor for a simple relaxation oscillator. B2 appears to be usually connected to the case.
Considering how a UJT is constructed, it should make little difference which polarities are used across B2-B2 except for what should be minor detail. Is that so? Is power dissipation or shielding affected by having B2 connected to the case?
Again, the UJT and JFET seem to be of similar construction except for possibly the heft of the main N channel. Can a JFET work like a UJT?
