What is the rationale for doing this?
I would think that it is not worth the effort.

The circuit topologies and concepts are similar, but the voltage and current levels are vastly different. As a practical matter, I don't think it is worth your time and effort to learn enough about tube circuits to even have a clue on how you want to approach the problem.

While you could build steel bridges from plans designed for wood and iron, what would be the point?

this ZINGU: AS MY INTEREST IS MAKING RADIO'S AS I GOT LOT OF SCHEMATICS AND CIRCUITS THIS WOULD BE SHAME HAVE TO THROW OUT ALL tRANSCEIVER I DO HAVE [[THUS I THOUGHT OF REBUILDING INTERESTING PIECES OF USEFUL CIRCUITS REMAKE USING SEMICONDUCTORS ! THANK YOU SIR

I only have this one :

 

Replacing vacuum tubes with transistors has been done and articles have been published. The rationality is that in many cases the hardware portion of a system is VASTLY superior to what is presently available at a reasonable cost. That rationality is not understood by those who place no value on mechanical integrity or durability. So there can be a great value in converting the better quality tube type receivers to solid state receivers. BUT constructing new equipment with modified circuits will not provide as great a benefit. And every bit of using old designs with modern components demands understanding of the new components.
Certainly there is a lot to be learned from understanding the older schemes, but that is not a substitute for understanding how to use the new components.

 

That older tube-type gear was designed for reliability first, then for performance. And it very often did last a long time under rather brutal conditions. It was never designed to be the cheapest possible product only needing to outlast the 90 day warranty. And the unit in the photo shown in post #8 was obviously designed with the ability to do quick repairs close to the top of the list.

 

Hi
Please stay On Topic.

Actually, my comment about the hardware portions of older tube type equipment does relate to conversion to transistor substitution in such equipment.
