I pulled a Sq-D rectifier out of service for door chime service last
year that was still working but not needed that was built in 1934
pretty amazing how long some of that old stuff holds up.
I have a 1940s era  1000 watt AM  Collins transmitter up at  the
station we keep in reserve duty and it fires up every few weeks and is
strong as ever. I got pictures of it on my face book wall all fired up
with the tubes lighted pretty cool.
