The CA3046 / LM3046 were cheap until they stopped selling them.
Fortunately I have several tubes of them left.

I know about them and I'm glad they still make them, but they are not
cheap and are single-source.

Interesting, in Latvia. They are agnostic, or maybe random, about
using commas or decimal points as digit separators.
Australia, America and the UK use the full stop as a digital separator. The Dutch and the Germans use a comma. I don't know what the Russians do. I haven't worked there.
https://en.wikipedia.org/wiki/Decimal_separatorputs Russian and Latvia in the comma camp. They probably know enough to be able to pander to American expectations.
Kinda grim on Street View, typical Russia/former satellite sort of
look.
No surprise there.
