I am looking for a lower cost replacement for the 2:1 mux I am using
for video applications. I need a total of 6 muxes (RGB+Sync and L/R
audio). Right now I am using 2 of these for the 6 muxes I need.
Bandwidth is not a huge concern as I'm not using this for HDTV applications.

For matching, can you just press them onto a pcb carrier? Something
that plugs into a breadboard, and gives you three big copper pads to
contact? Assuming holding them down with your finger or even just
letting gravity do the work, it might be sufficient.

One could ask why I use TO-18's in this day and age, and I'd answer "because I
can." Really though, most of my projects are retro in nature, so TO-18 just
fits that look.

Just as a reference.. I presume you have the user manual for the board.
It mentions the power supply stages, and shows a diagram..

How practical repairs will be depends on the exact failure mode. Could you
tell us exactly what was done to induce the frying, and what symptoms
Easy enough to repair. Get two soldering irons. Using two hands (one
for each iron), heat both sides of the component, and lift it off the
board. Clean with desolder braid and solder on the new components.

Hello all:
How you do to create a .model device line from datasheet?
In some comercial apps there are some tools for do this, but (I think)
don't be in gEda.
I had looking for some doc to do this with no success, there are
something somewhere?
In concrete I need a .model for a UF4004 diode
