Just keep off MY lawn!
Yeah, this is the thing that keeps me from undertaking retro projects. Are the parts still available? I don't relish the thought of perusing some old landfill looking for old radio and TV chassis. What if, for instance, I wanted to build a simple superhet ham band receiver with a 455kc IF? Do those things (IF transformers) even exist anymore?
Maybe someday I'll get off my fat butt and look into it.
For amateurs, spark transmitters were no longer legal by the late 1920s.
I've got a bunch of QST from the year I was born, 1955. There are even some transistor projects in a few articles.
Almost any older parts can be found if someone is willing to look, pay the price, and test them before use. "Retro" is actually easier because the parts were fewer, bigger, and more easily substituted.
The REAL trick is to design around parts that are found, or can be obtained or manufactured easily.
There are plenty of online sources of older parts. Just don't expect to pay 1959 prices in 2019.
I've got every QST from the mid-1920s on, and some even earlier. Worse, I've read every one.
On the contrary, Old Age and Treachery always beat Youth and Enthusiasm(or Skill)
Build it DX will come!!!
Likely with 2N### (three-digit) numbered transistors!
I remember ordering some of those early transistors through the DOD's military supply system (NSN's) in the 80's.
1950's vintage Collins' Universal Radio Group (URG) HF system equipment used several.
I doubt there are too many of them left anymore... though I don't peruse parts catalogs.
I remember playing around with the CK722, and later a 2N107... Am I an "antique" yet?
