Fake Parts

Interesting.

I've actually done this myself when I couldn't find an exact replacement
capacitor. I took apart the defective one carefully and mounted a modern
close equivalent inside and resembled it into the circuit. It then worked
perfectly. I did it because of the capacitor's form factor and mounting
hardware.

I've also done this for an old capacitor which had triple caps inside one
case. Since I couldn't find a replacement, I fit 3 equivalents inside,
sealed it up again and voila!

But, I wasn't selling them.

I suppose someday, when someone acquires my antique and needs to replace the
capacitor, they might be astonished.

Many moons ago, I had an old car in which the rectifier tube died in the
tube radio. I replaced it with a solid state diode. Worked great! No one
would be the wiser until they opened the case.

For restoring antiques, where looks is very important, puting modern
caps inside the shell of older ones is the only way to go - most
especially in the case of the liquid electrolyte aluminums.
Rewinding burnt IF windings is a snap and ther can be no objections
unless the coil form got carbonized or cracked/broken making it
necessary to replace...
