Part of my job at work is to lend advice and sometimes find a replacement part to a vintage one.
In this particular post, I am speaking about a General Electric branded "stabistor", or "stable resistor".
Apparently, these multi-pellet (I assume that means multi-layer to some extent) diode devices claim to have a very linear conductance over temperature, which allow you to design a very stable push-pull output amplifier stage, despite temperature changes. These little guys compensate for temperature changes that cause the stage to drift, etc.
The part numbers are STB568 and STB569 and are almost the same part with minor differences.
My questions are:
Are they still manufactured under a different company, brand name, trade name, or device name?
Besides small signal diodes like the 1N914, are there any other exact or close physical replacements that are not specifically stabistors?
I appreciate any of the support I can get! Thank you much!
