The original release of the transistor was not an over night thing. Some dealers would only sell to businesses and some would only sell in quantity. As a teen I worked in a Radio & TV repair shop and could buy through the store account. They were not cheap but i did get my hands on a few to tinker with. I don't think the point contact was ever readily available. The early junction devices were easier to get. Anyway the first published transistor radio I am aware of was in 1950.
I made the first one using sockets so I could try different transistors. I used some transformers I have in the shop. It worked! I have several transistors in the bins that worked in the circuit. In order to do it right I will have to wind transformers and make the point contacts. More on that later.
You can see the second one is more complicated with all those pots adjusting the bias. What else is different? If you made this circuit with modern transistors it would not work because the Emitter - Base junction needs forward bias. Let's take a look inside the transistor.
The point contact on the other hand would have the slab soldered in place and then the cat whiskers positioned and attached. The two points must contact an active spot on the slab and closely spaced. You might set one wire and the not be able to set the second. This requires moving the first. When they are finally positioned they must be formed. The forming process will not be repeatable because of impurities and surface oxide ......
So you could have a line making cans and attaching lead wires. Another soldering the wires to the slabs and a third placing the wafers inside the cans and attaching them in place. This would allow more production in making the junction transistor. Faster and cheaper takes the market.
Anyway plans are always subject to change but the present plan is to build the two circuits and see how they function. transformers to wind and transistors to collect or make.
Let the fun begin.
