Hi!
I know Triode will do tube connectors and it got me thinking about something a little crazy, and thought I would ask it here.
Note this is not rhetorical - I suspect there are great reasons, and I just want to learn.
Why use solder to connect wires to terminations instead of liquid copper?
On can imagine with something like a spade lug, clamping the wire and lug in a fixture, then pouring molten copper of a small measured amount into the meeting point. Copper has a high melting point, but we'll within what a blowtorch can easily do in a small crucible.
I know that is a pain, but let's face it, audio is all about extremes.
The more extreme version is that one cpuld use a mold to fully cast the collector (the tube or spade lug) in place, and stick the wire in right after the casting pour.
