Default EA53 tube for HP410B VTVM?

Does anyone know where these might be available for a "reasonable" price?
The cheapest I've found them for is $45 for a used "pull". I have a nearly
new 2-01C in my ME26D/U but that won't fit in the probe in my HP410B. As I
understand it, some 410B probes came with 2-01C diodes and some came with an
EA53 probe and the two are not always interchangeable.


Have you considered a silicon diode and a filament resistor? I know it
isn't original, but it will work just fine.
