I built my own voltage stabilizer.

At the time, Moss had one that used a diode and a transistor as a form of a crude shunt regulator.

I used a LM2940–10 automotive low dropout 10 V analog regulator.

Sense and I have seen photographs of the guts of the newer electronic regulators. It appears they use a single voltage regulator with no other components around it.

As I recall,  These used a through hole TO 220 device with the legs bent over 90 degrees and no heat sinking.

Not ideal

All these analog regulators need proper capacitors on the input in output side of the regulator.

My regulator with the LM 2940–10 has been in use since probably about 2004 with no problems in a TR4A

I can give further details, schematics, etc. to people if they are interested.

And I as well.  I was thinking it should be a simple device, but had not
dug into the details.  I know that the single component won't be enough,
though.
