Default Point to point wiring

So your saying you want to build your new unit with "classic" point to point wiring, be careful what you wish for....

If you have some of the salvaged tektronix ceramic strips you can make something way neater.

You have to use silver solder, or it will destroy them.

One time soldering may be OK.
But if you need to replace a part, or make a modification . . .

They did not work well for that in my situations.

Hi V4lve lover,

Out of interest, I do have those, but they are glued to plastic supports that require a specific size hole in the chassis to be a tight fit. How do you fit yours?

Cheers, Richard

Suposedly the old Tektronik gear shipped with a small reel of solder, just for that reason. Some quite interesting history here:

Tektronix ceramic-strips

Special silver-bearing solder is used to solder wires and components directly to the notches in ceramic strips and has a composition of 60% tin, 37% lead, 3% silver. This silver-bearing solder should be used when soldering or repairing ceramic strips which prevents the silver bonded to the ceramic from dissolving in the molten solder. Failure to use the correct silver-bearing solder on Tektronix ceramic strips can result in failure of the silver to ceramic bond.

Many of the modern lead-free solders contain around 3-4% silver, so presumably the leeching of the solder from the ceramic should no longer be a problem?

Well, there's point to point wiring and point to point wiring...It has nothing to do with the method itself, but with the execution.
Btw, forget those TEK ceramic strips. They weren't made for twist and solder joints. And thats the problem, soundwise.
But it could be kind of an art, though.
