Bolt together circuit? - UK Vintage Radio Repair and Restoration Discussion Forum

Hi all,
Not posted for a while due to various matters beyond any ones control

However just found this in a pre war "Practical Mechanics", book.
I guess it never caught on? "vero board", would be the nearest modern equivalent but soldering required?
Just wonder how many other such schemes have been tried and failed

Enjoy,
Paul.

I wonder if the Radionic kits got the idea from this.

I suppose components with wires like resistors and capacitors could have the wires wrapped round a bolt but I wonder how you would do a valve socket?

For the period in question, valve sockets usually had screw terminal connections.

Yes, Paul, very intriguing & fascinating; I've never come across that method before. Mind you, I bet he had a 'Meccano' set as a child.

Interesting - looks like an efficient way to increase stray capacitance!

I always wear my Sunday Best when making a wireless set.
