Check out what I scored recently on the Polish version of eBay!
A 1972 vintage ZDZ Mini 4 scope. Definitely small and rugged enough to throw into your toolbox! Powered by 4 tubes, a handful of resistors and caps.
And it works! Triggering seems to work pretty much automatically.
Came with this.. "probe"..
Some controls..
Number plate..
And the insides:
The caps even have the retail price printed on the body! 40.50 PLN
That's a bit "How ya doin"
Thanks and greetings to all!
