I get NO reading of anykind between the top cap and pins 1 & 4......
according to the diagram pins 1 & 4 are the cathode/ filament and the cap is
the plate.... it should read like a dioad shouldn't it?

thanks for the replies... I have an old Heathkit Warrior Amp (4-811's)
and
it has two of these 1N2637's in it it had some hum so I replaced the
oil
filled cap. it still has a bit of hum so I figured maybe one of the
rectifiers might be bad.... need to fix it or Ill sell it as is for
about
250.00 has 4 brand new 811's

If one side of those things goes open, you don't just get a little hum,
you get a hell of a lot. They don't go leaky very often but you can use
the diode setting on a multitester to make sure of that.
