I do a bit of electronic tinkering. Recently I restored two Heathkit VTVMs, it was pretty easy to do and a lot of fun.
I set one of the Heathkit VTVMs up on my workbench where I do use it for circuit testing and diagnostics.
I'm slowly restoring an old tube type ham radio receiver. I'm currently replacing all of the paper and electrolytic capacitors. I haven't worked on it for a while so I really need to get back to it.
