My brother had an almost identical one - I played with it a lot as a 10 year old kid. That's how my career in electronics started. I didn't grasp algebra or Ohm's law yet, but still, I learned schematics and built circuits. We didn't have Commodores and all the fun '80s Western stuff until the '90s, after People's Republic of Poland fell, and our country started opening up to foreign tech, clothes, food and other consumer goods - those were wild times. Our industry didn't survive the disruption in economy, factories were going bankrupt or were bought out by international corporations, usually as a hostile takeover. Unemployment and inflation soared. Lots of people came out destroyed from this era, but some entrepreneurial types made fortunes.
That is pretty cool. Radio Shack in Canada sold a similar kit in the late 70s. This is pretty cool that they create simple amplifiers to illustrate how the transistor is used. A little non-intuitive that in the PNP circuits that have the + side of the battery at the bottom of the diagram, not the top. I believe in Western electronics, the negative voltage is always at the bottom of the schematic.
All the transistors are germanium low-frequency with 1MHz transition frequency. The IC has inside analogs of BC546 (soviet KT315) or MMBTH10. I had some details from these in 1990x when I was a scoolboy
I was never a fan of such electronics kits. I had a similar RadioShack kit from the very early 2000s. I much prefer building on breadboards and perfboards, since they're more permanent.
Even now i would love to get my hands on a electronics laboratory like that. Its actually a lot better than the unit i have! Top video 😊

I know because I went through that. That is when I left for USA. 🇺🇸 też jestem Polakie
@@ExpatProfessor ah, I thought you were born American and moved to Poland :)
@KeritechElectronics moving back and forth… cannot make up my mind
Nice. I've had similar kits.
Yeah, I am keeping my eyes open for some rare ones. And thanks for your educational videos that I have been watching as well!
Much better than the kit I had . A dc motor in a little race car, and a light bulb.
Every little thing helps. What country was that modest „kit” available at?

Good eye! I also have a Czechoslovak kit to film as well, let us compare in due time.
I still have one in the attic.
Hold on to it! 👍

Wow, thanks for the detailed research.

There is some magic 🪄 in seeing them all next to each other and waiting to be connected. Thanks!
Why spoil a good video with silly music?
Thanks for the feedback
Ex pat? You mean inmigrant don't You?
I am Polish-American. Two citizenships here.
Board placing is well done (like caps and antenna rod near each other), but the speaker terminals are STUPID (on the right instead of the left?).
Yeah 👍 they got tired designing the layout just before they reached the speaker 😂
You must be Russian, you said "the relay" instead of the correct "a relay" :)
Polish-American. I am suspended in between… ☺️
