Yes please Modman. I'm fond of history and curious too.

It sounds like you have some intresting stories to tell uncleboko.

How about a "Library Caveat" sticky thread for the Davidoff Library?

It could start with a caveat pertaining to magazine articles in general and then leave room for multiple article spaning historical tidbits and saucy details via comments from folks in the know.

Seems that could work nicely.

The tone row seems played out here, I'll rein in my harmonious dissonance.
If I post in this thread again I'm sticking to the circuit. cheers folks

Maybe we should move this discussion to a separate caveat thread about the article. I, for one, don't know much about the background of these different magazines. I'd love to know more about that. I also kind of arrived at the conclusion of suspecting articles without authors of plagiarism.

You may have a point there!

As promised, here is the PCB layout clone. Ready-to-Print PDF-files: SprintLayout6.0 file:

Nice work Manfred !!!

This is a perfect example of how a classic PCB should be drawn.
Currently, the autorouter (of the design software we choose) is left in charge of completing the connections, but the aesthetic part and the elegance of an old-school drawn board are lost.

Cheers,

Thanks for the compliment Jose,

these old school PCB clones are a hard and time consuming job but I love doing that.
It has something nostalgic for me and reminds me of the start of my career in electrical engineering in the year 1968.
Actually, the interest started much earlier in 1965 with an electrical experiment kit my parents gave me for Christmas.
How time has passed now I am retired for six years.

Thanks a LOT, the CD4049UBE is a great discovery for me

If I want to add a depth pot, I suppose it's goes where the trimpot is?

By the way, have you tried it?
