Hello Mates,

i'd like to plot a beautiful A2 schematic, frame it and hang on the wall.
I'm looking for a high resolution drawing to plot. 300 DPI on A2 paper 594x420

Something vintage and handmade would look awesome, maybe something vacuum tubes? IDK

Greetings, all suggestions are welcome

I might use a schematic from one of the early Tektronix oscilloscope service manuals.  There should be high resolution scans of the 547 available.  Or maybe from the 545 which had a distributed vertical amplifier.

Something vintage and handmade

If you want tubes, probably something radio, either an early RADAR or this, the steering circuit of the V2 rocket.

I like hand-drawn schematics (Bob Pease for example).

My all time favorite: Quad 405. Vintage, but not tube.

I was quite fond of, for a while, the symmetry in a typical T flip-flop:



here implemented in vacuum state.

Some analog computing maybe, from "Applications Manual for Computing Amplifiers for Modeling, Measuring, Manipulating, and Much Else" George A. Philbrick Researches, 1966

If you download the print PDF here
https://bama.edebris.com/manuals/tek/1s1/
You will find 11x17 (A3) color scans of the Tektronix 1S1 sampling plug in schematics. 1GHz equivalent-time bandwidth in the 1960s.
I think it should scale nicely to A2?

I have few work copies from the 80's, A1 maybe and I'd say that you do not want those, if not now then eventually.
It's like an effect decoration, it must really mean something or it becomes old, fast.

A2 is close to 50x70 poster, it's target audience is few meters away and effective time very short.
Old maps are a good opposite.
I'd pick something elegant and simple or something that is still unknown after few looks.

Should it be a single page or is mosaic allowed?

Dot per inch is not lines per inch, RoGeorge's example is a good one.
Black and white scan has its down sides but it's still clearly hand made.
If you then want those white spots inside black filled you must drop dpi.
But 300 dpi is much and gray scale doesn't need much.

Maybe something from the Apollo Guidance Computer
