Hickok & MaxiMatcher

send me a pm if anyone wants me to test tubes for free or match output tubes (6L6, 6BQ5, 6V6, and etc.).
 
Your posting of tube sources is very much appreciated. Do you know where I can get the dial specifications that would work on a Hickok 533A for a 7027A power tube? Thank you.

I found the following on an old chart for a 7027 on a Hickok 533:

Filament 6.3
Selectors JR5327-0
Bias 23
English 88
Press P4
Mut. Cond. 5000

I do not know how similar the 533 and 533A testers are, and there is no listed setting specifically for the 7027A. At least, not on this chart.
Maybe someone else can weigh in on this.
