Testing Western Electric on a 752a Hickok


Is it possible to test WE tubes (300b, 396a, 274b, 417a, 412a to name a few) on my Hickok 752a? the problem is that I don't have the dial settings for these tubes on my scroll sheet. I know that some tubes can be substituted: I can use 2c51 for the 396a.

If anyone has any suggestions or a site that has the information. Thanks
