Help with Heathkit IO-4510 O scope

[Murray Grandy]

Further to my first call for help. I should say that these 57-56 diodes look
like any other diode. Only diff is they are about 1/2" long, and 1/8" or so
dia. About the size of 1/2 watt resistor. Black, with silver band on one
end. Thanks for all the suggestions so far.
